It's very easy to use on a loom, and I'm only experimenting with a small pouch-like purse for my daughter, but there are many, many cool sites out there for inspiration on using this medium!And, just a few bags, makes a good amount too. This was only one bag's worth (pink bag from Top Foods/October Breast Cancer Awareness bags)
Here are the steps on how to make your own yardage:
Lay the bag out like so...
Happy creating! (Amazon Fresh = light green yarn, Grocery Outlet = bright yellow, Safeway = white with red and black accents, QFC = beige, and various local shops have a variety of colors... I found bright blue and red recently.)
Keep adding additional lengths to the un-knotted end of the chain, use as many bags as you want for more yardage.
