Ok gang, this is incredible information, even for experienced quilters like me.
Having problems with tension? Thread breaking and you can't figure out why? Got pokies? Your machine not stitching that beautiful straight stitch? Here is a video from The Quilt Show (Alex Anderson and Ricky Tims) that explains it all and tells you how to fix it.
This episode is free to everyone until December 31 2019, so share with your friends. I've set the video to start with the segment concerning machine tension, but you can watch the entire episode at your leisure.
