Here is a bed spread I made for a client. The fabric was a poly blend, felt like microfiber, and was slippery to work with. She wanted the spread to reach the floor - so it is very LARGE 125 x 110.
Since she came to a quilter, I assumed we would use the regular batting common to quilters. I normally use a 70/30 cotton-poly blend from Quilters Dream, select loft - not the thinnest. She had a big puffy comforter look in mind. Not going to happen with the my regular batting. With that in mind, I used an extra high loft batt - typically used for trapunto, which was even more difficult to work with. Quilted with a large, open design...it didn't shrink as much during the quilting process. Tight, small quilting would have created little pleats on the front and possibly on the back.
