what is this?? after doing a little research on crocheting with thread.... which eventually led me a to filet crochet patterns, which look kind of intriguing because they are worked in a grid system, which allows you to draw your own designs pretty easily. like this here tiger.
or this gun.
the instructions don't look that complicated, and once the basic foundation is set, then it would be really easy to draw your own graphic on graph paper, or in excel, and make it. instructions are here.
also, here's a little info regarding thread size, and how they are matched to the crochet hooks. the larger the hook number, the smaller the needle.
