The design on the fabric comes together in the center of the hexagons to form a kaleidoscope effect. You design the layout of the quilt with these half hexagons pinned together. When you have your layout, you unpin the halves and sew them together in vertical strips. When the strips are sewn together the hexagons with the kaleidoscope centers come together and the wonder happens.
This is the fabric I chose for mine. I thought the blues and greens would look nice in one of the bedrooms at the shore house. Some people used Asian fabrics that came out very interesting. If I did this again, I think I would choose a fabric with a bit more contrast for greater visual impact in the kaleidoscopes.
These are the pinned half triangles laid out on a table ready to be sewn into strips. I often feel guilty about leaving a project sit for so long as I did with this one. The pieces have been sitting in a plastic bag since last August. However, I have decided this can be a good thing. By leaving it alone for a while, I'm coming to it with a renewed sense of motivation rather than responsibility. Also, I picked this fabric out in the Spring and chose it for a summertime environment. Now that Spring is in the air again, I have much more motivation to work with it.
