I took a class on this it was for using a new technique using charm packs (110 charms) and 35 2 1/2" strips wof sewn together as you would binding. Take each block and sew to binding spaced about 1 1/2" apart. Then cut eat row into strips of 10 charms. Then sew rows together. It is a little complicated to write the instructions. In the class we didn't get a name for the pattern only that it was a new technique.
