I posted links for sites with templates for Jack-o-lanterns on my cooking blog.
I used to knit. I don't do it much anymore because: 1. I'm lazy and 2. I have too many feline "helpers". When I did knit, I think I was fairly good at it. I won a ribbon at the Kentucky State Fair once for a shawl that I made. My biggest problem was (and still is) that I lacked patience. The shawl was probably the most complicated pattern I ever did. Most of the time when I looked for patterns the ones that caught my eye included the words "quick" and "easy". The next thing I checked was needle size. For me, bigger was better.
Althea Merback in Bloomington, Indiana has gone in the opposite direction. She creates one of a kind miniature knits. Her creations are in scales as small as 1:144. Here are some pictured next to a dime. One of the most interesting is a cardigan (1:12) with Picasso's Woman in a Yellow Hat on the back. The sweater "was knit with 32 different colors of silk and 3 variegated cottons and all in all it took about 400 hours to make. It measures 1 3/4 inches across the chest and is 2 1/2 inches long. There are 45 stitches to the inch."
I don't know whether to be more impressed by the attention to detail she shows or by the fact that, according to her "about me" page, she is the mother of a nine-year-old boy and five-year-old triplets and still has the patience to do this kind of work.
CrochetPatternCentral.com is a directory of crochet pattern links. Some are recent, many patterns date back to the 70s or earlier. It also has a basic "how-to" section with tutorials and illustrations of everything from how to hold the crochet hook to basic and advanced stitches.
I'm putting this link here so I can find it easily again (my bookmarks are a jumbled mess) in case I develop the patience to try to teach crocheting to my Brownie troop.
