The possiblities are endless with the number of combinations that can be made with this set! They are quick to stitch and are quite elegant and delicate in appearance. There are 10 basic 4x4 designs in this set that have been rotated to make a total of 40 design files. A finished block can be made by using 4 of all one design, or use any combination of designs that suits your preference. This set is perfect for runners, centerpieces, and even a large quilt for a bed because of being able to mix and match the designs. Each finished block will measure out to about 200mm (8 inches). The number of blocks that can be made is amazing! Use all four of the same rotated designs which will give 10 blocks, use pairs for another 10, or use one of each for another 10 to form finished blocks. That is a total of at least 30 different finished blocks. In the picture of the project I made, I used only two pair of designs just to show an example of what can be done.
