One of my favorite embroidery design sites is having a grand sale. Each "set" of designs is $2.50.
Buy 2 sets and get 4 sets free= 6 sets total
Buy 4 sets and get 8 sets free = 12 sets total
They have many quilting sets along with a lot of vintage sets. You might want to check one out before the sale ends.

I have used these designs for a long time and they stitch out great.
