It's kinda complicated.. you're just doing a lot of sewing. You're basically wrapping and cutting off extra fabric. I'm looking at videos, and articles learning how to do it.
I know how to sew, but I don't think I ever have. Hmmm... maybe that will be my project... YES!!!! Bwahahaha!!!!!... so I have alot of jeans that don't fit me anymore. (what a shock) So I'll cut them apart and make skirts and stuff!
... I'm too uncoordinated to sew anything. We made pillows in Home Ec one year... mine is horribly misshapen. Imagine what my jeans would look like. Not a pretty picture.
