This may have been addressed on the board, but I need some help in deciding the batting for my 15 year old grandaughter's quilt. With my directions, she has cut out and pieced a fence rail quilt top. (I am thrilled that she is interested in sewing as my daughter is not. ) My GD is asking if we can make it on the fluffy side. I sewed her a quilt, but I used Quilters Dream request poly which is the thinnest loft. Is Mountain Mist Polyester batting an option, and if so, how do I quilt it, how does she care for it, and can I use the spray basting on it?
