I've used fleece on a ton of lap size quilts....fleece is about 55-60 inches wide, so that will be the width of your quilt. I agree, do not try to use spray basting but use a fair amount of pins. I would not try to use the ''birthing'' method as there will be some movement of the fleece ( cotton top and back and batting, all stick together ) since it isn't ''sticky''. I lenthen my stitch length a bit, use a walking foot to prevent a lot of fabric movement and just do a simple SID to hold the fabrics together. You can either do a turned binding....backing to the front....or use regular cotton fabric for the binding. I cut mine about 3 1/2 inches wide, fold in half...( like reg. binding ) and use a 1/2 inch seam. I just feel a wide binding looks better on the bulkyness of the fleece. I have fleece blankets that have been used for years with several washing/dryings, and they still look good!!!!
