They sew the quilt wrong side out with a small opening.Then turn the quilt right side out and close the opening.This eliminates the need to bind.Birthing...?well,not.
I felt like I had been turned inside out but I really haden't.

Nice little tute!

Grannie Annie you are funny! It is a strange term to me too and I will have to watch the Jenny's video to see this. I can't imagine this on a big quilt but each to their own, I guess.

You can do it on any sized quilt. WEll, any size you are willing to wrestle with, as a big quilt would be a wrestling match.

LOL, I've done it for years without giving the method a name. It always reminded me of a grotesque cartoon where the character grabs his upper lip, pulls it over the top of his skull and turns his head inside out. In the early 1970s I was using knit dress factory cut aways (10 cents a pound). The sew and turn method worked great on pieced double knit tops with that old stiff, fused batting and a woven back. I couldn't afford the knit binding available and woven cotton did not look good. When turned the quilt/comforter had a nice, puffed edge. The fused batting was nasty to work with but either tied or coarsely quilted the result was durable. At the time, with no www or quilting friends, I thought it out myself.

BTW There are many hideous examples of polyester double knit quilts/comforters but taking care to select color and pattern they could look quite nice. The price allowed many warm covers to be made in our no-longer-prosperous town.
