I get asked a lot about taming wavy borders and my best answer is to avoid them in the first place. You may already know what ‘squaring up’ means and may want a refresher. If you don’t then I want to offer a link to the best example of squaring up blocks I have found. Its a short video by Bonnie Hunter. In this video Bonnie shows how to square up a small square in a square block. http://quiltville.blogspot.com/2015/02/5quaring-up-square-in-square.html
Squaring up the blocks before putting them together will help avoid the excess on the outside edge of your quilt. Fullness issues generally begin in the center of the quilt & amplify the problem until it gets out of control right before adding a border.
As you put your blocks together continue to lay the quilt out on a flat surface, the floor works great, and see if things are laying flat as you go. If not, fix the problem. If you don’t it will only get worse the farther out you go.
In addition, I like to suggest using some spray starch or sizing when you press your fabric before cutting it out. This will help keep the fabrics from stretching when cutting & piecing.
Enjoy the video & if you haven’t been to Bonnies blog you are in for a treat!
It may be too cold to go out, but its never too cold to quilt!
