I know some of you sew your batting pieces together. Be aware that it CAN be a problem for your longarmer (lAer). I had a customer send me a king size quilt with batting --- insisted he "had the batting" --- well, he pieced it. By the time I worked my way thru the king size quilt -- here's what it looked like. I had to cut the stitching off the batting, drag my ironing board out to the shop and iron on the tape that binds batting together. Not an easy task in a room that's barely deep enough for my quilting machine! I had laid it out on the table before rolling it up on the bars --- but the warp didn't show until toward the end of the quilt!!!!
