The body will be around 10” , however you can make this spider bigger or smaller by changing your hook size. The important thing is to make nice tight stitches.

This does not take a lot of yarn. The exact colors used on this spider are listed in the pdf. So if you don’t have a full skein of these you will be more than fine. I didn’t figure out exact yardage when I made them the main colors (purples) didn’t even use half a skein.
