I think my tuffet turned out well. The colors/fabrics that I selected are very me. Creating the top wasn't very difficult or time consuming, but it would have been easier if I had previously done foundation piecing (you sew the visible fabric on to muslin). No fancy sewing machine needed. You just need a straight stitch.
I was fortunate to take the class from the pattern's creator, Myra Mitchell, along with Linda French at Quiltworks NW in Bellevue, WA. The pattern isn't sold online, but you can contact Myra via email or call her at (425) 392-5798 to purchase (or you can contact QuiltWorks NW if you prefer). If you are in the area, I'd keep my eyes peeled for their next scheduled class session. The ladies explained that you can scale the pattern up or down, and Myra even has a version of the pattern if you want to make a square tuffet (also 18" x 18").
If anybody falls in love with my fabric selections, here is the list of the collections used:
Tula Pink's The Birds and the Bees (everything but the following)
Dear Stella's Piper (the purple zig zags)
Gail Kessler's Dimples (the dark teal fabric)
Michael Miller's Ta Dot and Dumb Dot (the two polka dots)
I purchased all of the fabrics except the Dumb Dot at Pacific Fabrics.
Now I just need to plan out my fabric for my 2nd one!
