I made these slippers because I wanted to use up some yarn I had. I try not to go and buy too much new yarn if I have some at home already. I guess for these slippers this yarn is not the best one to choose. I think it was lion brand wrosted weight yarn. Not sure. I got the instructions from the web. It is very easy to crochet and quick too but to put it all together is a bit tricky. I have 3 more different patterns for slippers I want to try out.
