"How about using invisible thread if you don't want the wayward stitches to show? I've never used it myself so can't tell you anything about using it."
Because my quilting instructor touted the qualities of invisible thread, I used it on my first quilt top. After several washings and dryings, the heat has melted the thread in many places so that - sometime - I need to re-quilt it. I did SID. Most irritating to say the least. The instructor never mentioned it was unsuitable for a quilt that would be washed/dried often!
