Sweater to Cardigan:
What you'll need:
1. A sweater
2. Hem tape (I used Stitch Witchery and it worked great)
4. An iron
5. A button and thread (optional)
And here we go! First, lay the sweater flat and cut down the middle of the front of the sweater (this is the opening of the cardigan)
Next fold over where you have cut and determine how much of a seam you will want. I folded it over about and inch. Place the hem tape on the inside part of the sweater's hem. Fold the remaining fabric over on top of the tape and follow the instructions on your hem tape.
My instructions say to put a damp cloth over fabric and iron taped area. It is important to not drag the iron, rather press bit by bit.
Find a button of your choosing and sew it on wherever you like. I made mine just for show, but if you're real ambitious you could add a hole on the other side and make the button functional.
Thats it! You're done, now go wear your "new" cardigan and try to stay warm this winter!
