I have adapted one of my antique thread keeps! You can fit 5 spools of 100/3 inside. Be sure to pop the top of each spool before you run the 2 yards of ribbon through them! Ten pages of instructions with 6 stitch graphs and step by step stitching and finishing instructions. You will be surprised how quickly you will finish this. There are 4 graphs for you to chose from for the Thead Keep cover.
