Transforming Sweaters: Create Your Own Tank Top

There are many ways to turn a sweater into a tank top. One way is to cut the sleeves off, measure the armholes, and cut a strip of ribbed fabric to fit. Then, sew the fabric into the armholes, and you have a basic sweater vest. For a more advanced project, you can cut the sweater to your desired length and turn it into a cardigan. You can also put the sweater on like a tube top, mark where it needs to be taken in, sew along the line, and cut off the excess fabric to make a tank top.

Cut off the sleeves

Cutting off the sleeves is the first step in turning a sweater into a tank top. It is important to choose a sweater that fits you well. The sweater can have a solid front or a button-up front. It is also preferable to have a V-neck, but this is not necessary.

Use a pair of fabric scissors to cut the sleeves off. You can extend the cut slightly below the armhole, but be careful not to cut into the front or back of the sweater, as this will make it too big. It is normal for the sweater to unravel a little at this stage.

If you are unsure about the length of the sleeves, it is better to cut them a little longer, as you can always trim them shorter later. You can also add buttons to the front of the sweater for a more polished look.

After cutting off the sleeves, you will need to measure the armholes and cut a strip of ribbed fabric to fit. This will be used to create the armhole binding. The width of the strip will determine the width of the ribbing on the armholes, so cut accordingly.

The next steps involve preparing the ribbed fabric strip and sewing it to the armholes. By following these steps, you will have successfully cut off the sleeves of your sweater and be well on your way to creating a stylish and comfortable tank top.

Measure the armholes

To measure the armholes, first, cut the sleeves off your chosen sweater. You can extend the cut a little below the armhole, but be careful not to cut into the front or back of the sweater, as this will make it too big.

Next, measure around both armholes and add these measurements together. To this total, add 2 inches (5.08 cm) to allow for seam allowances. This final measurement will be the length of the ribbed fabric you will cut for the arms.

Cut ribbed fabric

Cutting ribbed fabric can be a tricky task, but it is important to get it right to ensure your garment hangs nicely without twisting. Here is a step-by-step guide to cutting ribbed fabric for your tank top:

Firstly, you need to identify the "right side" of the fabric. This is the side that will be visible on the outside of your garment. The right side of ribbed fabric will have tiny vertical lines or 'ribs' on the surface, while the wrong side may look like it has a horizontal texture. If you are still unsure, the selvedges (woven edges) of the fabric will curl towards the wrong side.

Next, you need to figure out how to fold your fabric for cutting. Look at the fabric cutting diagram for your pattern and see if it requires one fold or two folds with the selvedges folded into the middle. Fold your fabric loosely according to the diagram to start correcting the fold line.

Now, you will work on perfecting the fold. You want to line up the little vertical striped rib lines along the fold. Pin along the fold line to keep the ribs in place. Continue pinning until the entire fold line is pinned. If your fabric has two folds, repeat this process with the second fold.

Once you have your fabric folded and pinned, you are ready to cut. You can use regular fabric scissors or a rotary cutter, which looks like a pizza cutter and gives a more accurate result. Simply roll the rotary cutter firmly along the cutting lines, being mindful of your fingers and the sharp blade.

And that's it! Your ribbed fabric is now cut and ready to be sewn into your tank top.

Fold the fabric

To turn a sweater into a tank top, you will need to cut the sleeves off. Use fabric scissors to cut the sleeves a little below the armhole, but be careful not to cut into the front or back of the sweater, as this will make the armholes too big. It is normal for the sweater to unravel a little at this stage.

Next, measure the circumference of the armholes and add these measurements together, plus 2 inches (5.08 cm) for seam allowances. Cut a strip of ribbed fabric to this length, and 2 to 3 inches (5.08 to 7.62 cm) wide. The width of the strip will determine the width of the ribbing on the armholes, so cut according to your preference. You can cut the material from a matching sweater or from cotton ribbing.

Now, fold the strip in half lengthwise twice to make a double-fold bias strip. First, fold the strip in half lengthwise with the wrong sides facing in, and press it flat with an iron. Next, unfold the strip and fold both long edges towards the centre by ¼ to ½ inch (0.64 to 1.27 cm). Finally, fold the strip shut and press it flat with an iron again.

Cut the strip in half widthwise. Fold both ends towards each other and cut at the fold, so that you have two equal-sized pieces. Unfold both strips once, so that the long side edges are still folded towards the centre crease. Now, fold the strips in half widthwise, with the right sides together, and sew along the narrow edges using a ½-inch (1.27-centimetre) seam allowance.

Sew the fabric

Pin the rings to each armhole, tucking in the raw edges inside. Fold the top edge of each ring over the raw edge of the armhole, sandwiching the armhole inside, and pin the rings in place. Sew the rings down, choosing a narrow, zigzag stitch and a thread colour that matches the ribbed material. Sew all around the ring and armhole, about ⅛ to ¼-inch (0.32 to 0.64-centimetre) away from the inside folded edge. Be sure to sew through all layers of fabric and remove the pins as you sew.

Finally, press the armholes with an iron, tucking the iron into the sweater to smooth out the back and front armholes. This will ensure that the ribbed binding layers nicely against your sweater and prevent creases from forming at the shoulder and armpit.

Sew the fabric

To turn a sweater into a tank top, you'll need to do some sewing. Here's a step-by-step guide:

Prepare the Sweater:

First, choose a sweater that fits you well. You can use a sweater with a solid front or a button-up front. If the sweater has sleeves, cut them off using fabric scissors. Make sure not to extend the cut below the armhole towards the front or back, as this will make the armhole too big. Don't worry if the sweater unravels a little.

Create the Armholes:

Measure the circumference of the armholes and add these measurements together, plus 2 inches (5.08 cm) for seam allowances. This will be the length of the ribbing for the arms. Cut a strip of ribbed fabric according to this measurement and make it 2 to 3 inches (5.08 to 7.62 cm) wide. The width of the strips will determine the width of the ribbing on the armholes. You can use matching or contrasting colours for an interesting look.

Now, it's time to prepare the ribbing. Fold the strip in half lengthwise twice to create a double-fold bias strip. First, fold it with the wrong sides facing in and press it flat with an iron. Then, unfold it and fold both long edges towards the centre by ¼ to ½ inch (0.64 to 1.27 cm). Finally, fold the strip shut and press it flat again. Ensure your iron is set to the appropriate temperature for the fabric.

Cut the strip in half widthwise, then unfold both strips once so that the long side edges are still folded towards the centre crease. Fold each strip in half widthwise with the right sides together and sew along the narrow edges using a ½ inch (1.27 cm) seam allowance. You now have two loops of ribbing for the armholes.

Pin the ribbing loops to each armhole, tucking in the raw edges inside. Sandwich the raw edges of the armholes between the folded ribbing, ensuring they align with the centre crease. Fold the top edge of each ribbing loop over the raw edge of the armhole and pin them in place. Make sure the ribbing seams align with the sweater's side seams at the bottom.

Now, it's time to sew. Choose a narrow zigzag stitch and a thread colour that matches your ribbed fabric. Sew around each armhole, about ⅛ to ¼ inch (0.32 to 0.64 cm) away from the inside folded edge. Be sure to sew through all layers of fabric and remove the pins as you go. The zigzag stitch should be narrow, almost a straight line, or you can use a stretch stitch.

Finalize the Armholes:

Press the armholes with an iron one more time. Tuck the iron into the sweater and iron the back and front armholes on each side to ensure the ribbed binding layers nicely and to prevent creases from forming at the shoulder and armpit.

Optional: Add a V-Neck Collar

If you want to add a V-neck collar, draw the desired neckline on the front of your sweater. You can eyeball it or use an existing sweater vest as a guide. Cut the V-neck, being careful not to cut off too much material at the sides and back of the neck hole.

Cut a strip of ribbed material long enough to pin along the new neckline, adding 1 inch (2.54 cm) for seam allowances. The strip should be 2 to 3 inches (5.08 to 7.62 cm) wide, matching the width of the armhole ribbing. Fold and press the strip twice to create a double-fold bias tape, as you did for the armholes.

Unfold the strip once so that the long edges are still folded towards the centre crease. Cut a V-shaped notch into each end of the strip, ensuring they are aligned. Sew the notches together by folding the strip in half widthwise, pinning the V's together, and sewing with a ½ inch (1.27 cm) seam allowance.

Pin the collar to the raw, cut edge of the sweater neckline, slipping the loop over the neck and folding the top edge over the raw edge. Make sure the point of the ribbing aligns with the point of the collar and pin it in place. Topstitch the ribbing down, using a thread colour that matches your fabric and a narrow zigzag stitch. Sew around the collar, ⅛ to ¼ inch (0.32 to 0.64 cm) from the inside folded edge, removing pins as you go.

And there you have it! You've successfully turned your sweater into a tank top. Feel free to add any final touches or decorations to make it truly yours.
