To fix the wavy borders, I added three more rows of quilting to the borders of Tumbler quilt. The extra quilting drew in the edges of the quilt.
Next I ripped the binding off. I spritzed the borders with water and pressed them, and then pinned the binding back on the quilt. When I re-sewed the binding to the quilt, I cut about 2.5 inches off the binding. That's how much the extra quilting shrank the perimeter of the quilt.
I finished the binding by hand. No more wavy borders. Next time I will be more careful with how the quilting density is distributed across the quilt.
Now that the Tumbler quilt is fixed, I have been working on machine quilting the Charlie Harper quilt (the colors were inspired by a Charlie Harper print). The pattern is 'Tumalo Trail' by Bonnie Hunter. Two biologists saw me practicing the quilting design on the whiteboard outside of my office at lunch one day and they both said 'algae'. I ran out of thread before I finished the quilting on this one and had to order more. It took 6 hours and 40 minutes to machine quilt it.
I also finished sewing the quilt top for the quilt on the design wall behind the sewing machine in this photo, but I ran out of cotton batting so I put it away for now.
