Oh, lucky you!
I took a short (3 hour) class last year and enjoyed it, but it's not an inexpensive hobby - and between quilting and cross stitch, I've already got enough toys and supplies around, so havent wanted to sink any more money into another craft. Without the gripper hoop, it's not easy - so I'm sticking to what I have and know.
Your seat cover is lovely, would love to see a picture of the stair covers.
