I didn't make much more progress but I think I have made my decision to use these pieced squares borders. At first I thought they were too multicolor but I like them now that all 4 are made. They aren't sewn on yet.
Here is a reminder of the quilt in "the Modern Medallion Workbook". I think I may add a 2" border between the border above and the last border.
The outside border takes 2.5" wide pieces so I got out my box of Kaffe collective strips.
If I add a purple border next the outside border will be all reds and pinks. I found this variety in the box. I'll look for some more that have red and purple in them.
