Braided Chair Pads and Rugs Using T-shirts

several braided rug tutorials here

Here's a video made showing how to cut the material into one long strand rather than many strands you have to tie many knots in to connect. She shows you how using a plastic bag but the principal is the same. Any item you have that is a tube can be done this way.

T-shirt cut off below the arm holes or skirt,pant legs,pillow case or shirt sleeve - it doesn't matter as long as you begin cutting a tube as shown you end up with one long strand!

sorry to ramble
P.S.
I use her method all the time to cut my plastic bags down to crochet with. If you are new to this you might not realize to not cut as wide as she cuts in the video if you want to use a smaller hook but because the plastic scrunches down pretty well you might be ok - you might want to do a test strip to see what size you need to crochet with the hook you plan on using

Use the web search engine and type in "braided rug instructions" or "hooked rug instructions". I got some good results. Good luck.
