Someone please help me. I only machine quilt. I use the walking foot. I can do backing fine on potholders, place mats and table runners but anything bigger than that and I get creases in the back. I am always pulling out. It is never smooth. I pin and pin and pin so I don't know what I am doing wrong. Is the only solution to keep cutting the thread, taking a look underneath and then reconnecting thread? That doesn't seem practical.

I starch my backing pretty stiff and then use spray baste. I also pin about every 8-10 inches. This is the only way I can do anything larger than a runner. Otherwise I also get the tucks and pleats. Good luck!

I starch the dickens out of my backing.
Then when sandwiching, I tape or pin down the backing, slightly pulling it so it is taught, but not stretched. Then add the batting and the top.

Also, make sure that you are pinning/basting it closely enough, too :D:D:D

There is a quilt on one of my dinning room chairs for more than a year because of a BIG crease. I was hand quilting it and did not look at the back. Oh my. On my bucket list.

Starch then tape( use masking tape or what ever tape will stick to your floor.).. the backing to the floor firmly not stretched making sure there are no creases then put batting then quilt top... Pin about every 4 inches... Once pinned remove from the floor and turn over and check that the batting is smooth I sometimes have to repin some sections.. another way is to use bull clips to hold the backing onto a table then pin batting etc

If you use the Sharon Schamber method you don't have pleats and you don't have to get down on the floor either.

You may not be pulling the back taught enough before you pin.

Pulling the back too tight can cause wrinkles too.

If you use a table, there are large clips that you can attach to the edges that will help keep your backing fabric tight (not too tight), providing that the clips fit on the edge of the table!

Thank you for the Sharon Schamber method. I am tired of ruining my fingers and nails with pins. I am off to get boards and try this method.
