Ok I have a question- I've never had this happen. I sandwiched a baby quilt but evidently I didn't get the back taunt enough I tried to hand quilt that didn't work. I wanted then to just tie it but will it work? I did the pillow case method of sandwiching. Do I have to take it apart ?

I think it would depend on how much excess fabric there is on the back if its quite alot then I think you would probably have to take apart - sorry!!!

Agree it depends on how much excess fabric is in the back. You could tie it, but how far apart the ties need to be depends a lot on the batting you used. If the ties are too far apart, the batting can start to come apart and ball up inside the quilt with every washing.

Ok I took everything but the edge stitching out and pinned it looks mucho better! Duh! I don't know y I forgot u baste or pin! Brain fart? Lol

If it still looks too loose along the edges after you get the tacks in, can put a binding on to cover the back vs front difference.

You will be glad you took it apart. Can we see it when you're done?

it depends on the batting!!!
some batts are good for tied quilts and say so on the packaging- some batts HAVE TO BE QUILTED every 2"-4" (very densly) other batts allow up to 10" between stitching lines- those are the ones that work for tied quilts.
when tieing you need to have your ties about every 4"- anyplace you put your fist should touch a tie- top, bottom, side to side (in a grid)

Maybe a pic will help all of us know???? :)

I have never been happy with the pillow case method of sandwiching. It always manages to shift. I have found the best method for me is to iron the sandwich and get it matching as close as possible. Then I pin it all over, start quilting from the middle out and leave about a 2 inch unquilted border all around the quilt. The unquilted border allows for any extra fabric to be less noticable because it puffs up a little. This would also work if your tieing it, just make sure to follow batting instructions for the space between ties.
