How many cross stitch books do you own and how often do you use them?
I didn't count, but these bookshelves were built into the corner of my sewing room (to ceiling and around corner to the left). These two shelves are the mainstay of XS books, but I have a bag from BH&G Craft Book Club full of the ones I use the most. The other shelves here hold stuffed magazine holders, baskets with fabric, etc.
I use the Stitcher's Bible regularly, but I found the one dog-eared book I've used the most is the one below, Basics and Beyond, which is how I taught myself hardanger. Great book!
