I have been crocheting now for a while and decided to expand my knowledge. I only know how to do granny squares I was taught by my great grandmother. I have been looking for different ways to crochet and I have been watching lots of videos on YouTube of how to's. One thing that interests me though is arm knitting or crocheting. I really want to make a blanket but I seems so high priced most all tutorials I have found call for 8-10 lbs of jumbo chunky yarn. The cheapest I have found this yarn is $80 for 4 lbs. Do I really need this much yarn? Also is there anywhere to get it cheaper by chance or did I find about the cheapest?
