Ohdeedoh has provided so many wonderful options and seems to have mythical Etsy searching skills.
Today I am particularly taken with 2 options though. Number one is Nerd ABC's my beloved husband is such a nerd this seems perfect. Only issue is they really don't fit the theme.
A few days ago I saw a nursery which used fabric stretched on canvas for art which I liked, but today I stumbled across Nested and found this post which, like me, is deeply by Soulemama's use of embroidery rings for fabric pieces. Perfect for unique art & style! I love it. Off to check eBay for Embroidery rings and hunt for perfect Fat Quarters.
