This year for the teacher thank you gifts I decided to give coordinating card sets. Each set includes 5 matching cards with envelopes (each card with a different greeting). For these very simple cards I cut 3"x4" pieces of pretty patterned paper and then straight stitched around the edges with my sewing machine. I then glued the paper down on a white card and added a greeting stamped on an oval and framed with a scallop oval. The result is very clean and simple.
