How to make the edge of tufted rugs not look wobbled?

1, Make it as straight as you can on the frame. I use a level and will pull my grid to make it straight before I glue. Then when you glue your backing on you have to do it all over again. It’s a lot of work.

3, Cuting the backing to size before gluing it on.
