The pattern directions for this book cover quilt uses a 22.5 wedge ruler and the 12 basic colors on the color wheel. Within the 12 colors you select 8 values from very pastel to the darkest shade totaling 72 6 1/2" x 1/12" strips sewn together to make 12 strip sections.
I have photographed the book instructions to show how the wedges are cut. Add a piece of white to create a Dresden top to each wedge.
I though I followed the instructions and I ended up with only 3/4 of a circle. I started doing the math. A circle is 360 degrees divided by 12 wedges = 30 degrees not 22.5 as in the ruler width the book suggested. I reread the directions, got advice from my online quilting group and even emailed the book publisher who never got back to me. So I didn't want to scrap the idea so I make four more wedges to complete the circle and I was happy with the quilt and could finish it! My intentions for this quilt is to use it as a visual tool for my color and value classes.
When originally selecting the turquoises I was leaving out the teals, and when I was picking out red violets I was missing out on the warm pinks and when I was choosing the lime greens I was not getting any of the great chartreuses so this was an easy task. I then added the fourth wedge with golds.
I am happy with the quilt but will not do this again and art is more fun than busting my brain on this math and geometry stuff!!
