One of the things I was thinking about was eyes, and how to make them myself. I had several packages of covered button forms, and made up two pair of eyes using them. I like the way they turned out, and created a tutorial:
Covered Button Eyes
Mine were made with 7/8 inch buttons, but you can use any size you want. All you'll neeed are the button forms, some scraps of white cotton fabric, acylic paints in white, black and iris color, and gloss or satin acrylic varnish. These eyes would work for any doll or animal, in cloth, crochet, or knit.
As for Rachael, I used size 4 dpn's to knit her body, instead of the 7's called for in the pattern. The yarn is Caron Simply Soft, which I do not like for crochet, but it knits wonderfully. I wanted a smaller doll than the original, so I took out eight rows from the body, and will take eight rows out of her legs and arms (I think).
Enjoy your dollmaking day!
