So I really like this pattern. It's the Market Bag pattern at Lion Brand Yarn's website. It's for their cotton yarn, but I did it with plastic bags. Because of this switch, I also used a "J" hook instead of the "H" they call for in the pattern.
Normally, I use softer/more pliable plarn (plastic yarn). It's easier to use the kind that WalMart bags are made of, mainly because they're almost all made of the same weight of material. This bag, though, is made from all those other plastic bags you get, such as: bread, carrots, toilet paper, paper towels, red beans, celery, tortillas, dry cleaner bags and many, many others.
This makes for a much slower construction. It also yields a slightly lumpier finished product. Over time I think it will smooth out some. The bottom flattened out a good bit after just the first use.
The bag is rather large. It's 14" wide at the bottom and about 19" tall (including the handle). It has a little stretch, but not much. Unlike other reusable shopping bags, it doesn't fold up really small or anything. He's a very sturdy little fellow though, and I like his colors.
My photography skills leave something to be desired...ah well. I'll get better one day. :)
