If it were me, and I do a
lot of fused art quilts, I wouldn't use it. I wouldn't even use the lite version. Three layers is going to be hard for a machine needle to get through and impossible for any hand stitching. Don't let the wrong product ruin your experience.
I stopped using SAS a long time ago and switched to Pelon 805 (Wonder Under) and Misty Fuse. Two of the many benefits are no more gummy needles and I can hand stitch through 3-4 layers of either one.
Very nice work on your class project!
