I recently finished Karen's quilt. With this being a traditional sampler-style quilt, the challenge was how to create differentiation between the blocks, yet find unity so it all belnds together in a singular piece. In this case, I mostly used feathers and several different curl patterns, among a few others. I especially liked how the border came out, with lines radiating out to the edges with curly cues on each side.
In the full size pic below, one can see how the feathers and curls worked together. The center panel also has curls. Yet within the center, I used two different curls, one being more dense than the other. This provided further differentiation within the block itself.
I really like when customer jobs like this come in. The opportunity presented by a creative puzzle is not only challenging, but extremely satisfying when the puzzle is solved and completed.
