Quilt top border seems stretched
Added the 5 in. border to my scrappy quilt and for some reason it doesn't lay flat. Think maybe its not 100% cotton could that cause the edges to not be straight? Wondering if it might have polyester in it.
Any suggestions how I can rectify this without ripping it all off? Other thought is even though I cut the edge straight could it been crooked? Any suggestions would be very much appreciated.
