Anyway, in the past, my knees and back used to suffer sandwiching quilts on the floor. It worked. There were no puckers on the back of my quilts. But, boy did it hurt.
Eventually, I did end up putting two folding tables together and using lots of masking tape (same as I did for the floor), but puckers were always there, no matter how much I tried to keep the backing taut.
Enter Styrofoam boards and flower pins.
This quilt is the last one that I did using this method. Binding has yet to be cut and sewn on, so no full photo of this quilt just yet.
Then, the right side of the backing was stretched slightly and pinned in place. Lots of flower pins about every 2". No pins were placed on the side that is closest to the quilt you see hanging on the wall. The batting and top were placed on top and then I could start to pin baste.
The flower pins stay pinned into the Styrofoam. The process of pin basting (using quilting safety pins) can start.
Once I moved the whole section forward towards me, I don't bother placing any flower pins where you see the arrow. Gravity does a wonderful job. Flower pins are placed on the backing (just the backing), starting on the left side and then stretching the backing slightly and more flower pins are placed on the right hand side.
The down side to this? Miss Ashes can't help me anymore. She is not allowed on the dining room table. Lordy, but she sure does protest this new method! LOL
Next time I sandwich another top, I will use strips of wood on my top just to make the smoothing easier each time the section is moved forward.
Like I said, I'm getting smarter.
Have a great day!
