I thought about getting a loom but am currently seeing how frugal I can be. The frames to weave a rug are actually very simple the internet and youtube have all kinds of info.
I have found that the "toothbrush" rug is the easiest rug to make . Second to that is crochet rugs if you know how to crochet. Look up the toothbrush rug, It will make you want to start tearing up all the cloths and old sheets in the house lol. Super simple, all you need is a clothes hanger,duct tape and rags! This is a wonderful site to start.
