I made a borderless quilt recently. Sent it to be long armed and until I read this thread I never gave a thought to potential issues. I did stay stitch the edges. I saw a quick photo of the quilting and I'm thinking the binding will be a challenge where feathers extend to edges. I have my fingers crossed that my excellent long armer took that into consideration. It comes back soon. I always get so much good information here. Next time I'll be thinking about the details of making quilts borderless.
