If you’re like me, you end up ripping a lot of seams. Sometimes it’s from dumb mistakes, sometimes it’s just part of a quest for perfection. This is the fastest, safest way that I’ve found to rip out a straight single stitch seam.
On one side, rip out every 5th stitch or so.
Then take the thread from the other side and pull. Wham Bam Thank You Ma’am. Fewer worries about snagging the fabric with your ripper. Easier to fully remove the bits of thread that are left.
