With this pattern you can create your own Lucy doll! The pdf has detailed instructions and tons of photos. There is no gauge to this pattern. You can use the yarns you want - just adjust your hook accordingly. I used sport weight cotton yarn with a B hook and she stands approximately 6 1/2 inches tall. This doll is also made with crafting wire so that you can pose her however you would like! Instructions for that are included in the pattern.
