I learned to crochet when I was about 7 or 8 years old. My grandmother taught me how to make a chain and I would see how long I could make the chain by laying it on the floor and seeing how many rooms I could chain through. Then my grandmother would cut out circles of cardboard and I'd glue spirals of chain onto them and make "dollhouse rugs". This is as far as my skills went until college when my grandmother taught me the single crochet and I had one ambitious year where I made everyone single crochet blankets and purses and scarves. I still would say I'm not an expert when it comes to crochet but I do have better skills than that little girl I use to be!
This is one of my latest creations that I made for my older son (a huge Thomas the Tank fan) and a good example of why I like to crochet. Thomas is mostly just made up of simple shapes and I find crochet is much easier way to make simple shapes than I can with knitting. This Thomas is made with all single crochet and most of the pieces were workied seperately and then sewn together after it was finished. The face is just a product of a piece of felt and a sharpie marker that was sewn on at the very end. He isn't perfect by any means but both my sons love him and that's enough for me!!
