I do a lot of fusible, raw edge applique and have always used Wonder Under Lite (or Medium if Hancock's is out of Lite). I have a friend who teaches at a vo-tech here in Oklahoma City and she always used Heat and Bond Lite and has no problem sewing through it. Are you doing hand quilting? If so, even the Wonder Under Lite may be difficult. I don't do any hand work so I don't know. Also, I have used spray baste to hold things in place until I get them stitched down. BTW I love your framed quilts. I do a lot of wall hangings but have never framed them. Going to do that soon. Happy Quilting.
