I love the colors and the pattern. This is a fine first quilt. Your squares match up well. Whoever gets this quilt is going to be very lucky.

They still have them and use them 8 years later. My motto, from my father in law is "It'll never be noticed on a galloping horse and that's the only kind I ride."
Here is a video from Angela Walters that I think would be very beneficial to you.
