A great stash-buster class is "What's in the Box?" This is a fun way to use up the novelty fabric in your stash to make a popular "eye-spy" quilt or a theme quilt. You can choose to make it as small or as large as you want too.
"Woven Silhouettes" is a technique class that's mostly 'no sew'. Using Anna Faustino's beautiful book "Simply Stunning Woven Quilts" you'll learn how to weave and fuse a smashing background for any image you'd like to feature. Apply one of the silhouette patterns I'll bring or use one of your own then add borders and you'll have a lovely wall-hanging.
Turn the selvages you might ordinarily throw away into a useful charge-cord travel carrier or iPad or e-Reader case with my newest class, "Salvage Your Selvages"
"One-Fabric Kaleidoscope" from Maxine Rosenthal's inspiring book "One Block Wonders" is a class I've taught over 30 times. I've made 6 "Wonders" personally and have a lot of tricks for cutting, chaining the pieces, making them lie flat and designing with those amazing "blossoms" you end up with.
