I posted here about 2 months ago to get some advice on a quilt I was starting. Everyone was so helpful, I decided to seek your advice again. ;) I have completed the quilt top and backing. I have the quilt sandwich together ready to machine quilt. I plan on using a walking foot to "stitch in the ditch". I don't have a locking stitch on my machine, would it work if I bring the bobbin thread up and knot the two threads together and bury the ends into the quilt? Is there another method that would work better? Any help/advice is much appreciated! Thanks in advance.
