I saw on fons and porter where she brings up her bobbin thread, then advanced a teeny tiny bit, and made a stitch, almost in the same hole, she said. (a guest, I don't remember her name, I am sorry). She explained that it made it knot inside the quilt . . .
A kid was talking to me and I almost missed it . . . I don't feel like I got all of what I needed to know . . .
I usually knot my tails, before I buried them. One by one by one. LOVED this info!! ;0))
