Nice Job Melissa!! I love the blocks and the colors.
When I did my second quilt I pondered many days on how to Quilt it. It was a Timeless Treasures Rectangular block Rainbow color quilt Kit. The colors were primary in graditions of all the colors of the rainbow. I finally decided to get the multi-colored thread in primary colors and did a machine quilting. The material on the back of the quilt was also made by Timeless treasures and was tropical flowers with a sunset behind them in a large run and all the same colors as the front of the quilt. I was going to quilt in the ditch around the rectangles. But when I went to my quilting store they suggested a free form quilting. I thought that was a great idea so I machine quilted around the tropical flowers and leaves on the back of the quilt using the multi-colored thread in my bobbin and the top thread. Then on the 4 inch border of black I did a free-form quilting using curvey lines, kind of like the design in live brain coral. It came out beautiful, if I do say so myself. Just an idea for you. They do sell the multi-colored thread in all sorts of colors including dark raspberry to light pink.
