I would also lean toward using spray baste. I haven't used it for applique on a quilt, but use it frequently for embroidery machine applique, and it's nice, especially for those intricate shapes. Use very little, but move the can as you spray so that there's good, light coverage without it getting wet. If you haven't used it before, you might balk at the price, but a can lasts a long time. It may actually be more economical than fusibles, and it's definitely quicker.

I don't like to have a build up of these products in the air, even the ones that are labeled non-toxic, so I use them outside whenever possible. A large corrugated box makes a good work surface for spraying. Small bits can be pinned to it to keep them in position.
