Turn a plain pair of leggings into exciting statement legwear with this unbelievably easy slash and weave technique! I've seen this method used on a lot of T-shirts, but when I saw it recently on a pair of leggings I thought it looked so good that I decided I had to try it out. It isn't technically a braid, it's more like a crochet stitch, but either way, I was honestly shocked at how easy it was and how good it looked. It has exactly the kind of biomechanical aesthetic I love, like stylized spinal column or snake skin made of cloth. I will now have to restrain myself from attacking all my clothes with scissors, and giving them little spines!
All you really need to create this look is leggings and scissors, but a few other things help, and there are a lot of design options to play with. In this Instructable I'll show you what I've discovered so far.
Leggings to mod - Almost any leggings will work, but if you want to run this detail down the side of the leggings, it's better to use a pair that doesn't have a side seam. If your leggings do have a side seam, you can just create your detail on the front and back of the legs. Also, this detail will look best on leggings that are not super tight and have a good amount of stretch.
Scissors - make sure they are sharp enough to cut fabric well
Tailor's chalk - chalk that will wash off your fabric (unless you want to freehand your cuts)
Ruler - I find an 18"x2" clear ruler to be an absolutely indispensable tool for patternmaking and sewing, in fact I go pretty crazy if I don't have one, but you could do this without it
