So I though of that plain, boring (and cheap) cardigan that has been lying in a lonely corner of my wardrobe, and decided to make varsity cardigan out of it!
Step 1: Materials
3. Iron-on patches (you can use either numbers or letter!)
Note: The colours of the ribbon and the iron-on patches should be similar and complementary to the colour of your cardigan :)
Step 3: Cut
Step 4: Fold
Step 5: Sew OR Glue
Stick the ribbon in place using Heat N Bond! I wished I had some... but it's all right because the sewing actually gave the stripes an added effect as well. So it's really up to you.
