Over the years, I've used borders in a variety of ways. Even if you do not design your own quilts, Finishing School Better Borders with Winnie Fleming (affiliate link) does an excellent video job of explaining the various borders and the best ways to measure so that they lay properly for your quilt top.
Craftsy Quilting Courses
Free-Motion Quilting Essentials with Christina Cameli is a fabulous course to consider if you are just starting out with free-motion quilting. Christina covers all the basics for those just starting out.
I recently enrolled in Amy Johnson's Craftsy class: Quilting With Rulers on a Home Machine. Her class doesn't disappoint. It's chalk full of tips and tricks for using rulers with a domestic sewing machine.
I recently joined the Mini Quilt Mystery Club on Mishka's Playground. The club runs for six months and each month introduces a quilt pattern that finishes at 24".
Wow...well let me just start out with my summary: I love The Secrets of Free-Motion Quilting and I love Christina Cameli's teaching style!
One of the very first classes I purchased after joining Craftsy was Quilting Big Projects on a Small Machine (affiliate link) back in September 2012. I loved it.
I recently became an affiliate for Craftsy. As an affiliate, I will be compensated if you click on any Craftsy links on this website including those videos I review.
