Hi,
You can do many things with layer cakes.....I cut them in half both ways and then diagonally each square and made a pinwheel quilt....turned out great!
A honey bun is a roll of 1 1/2 inch strips.....Moda has them.
There are also fat rolls out there, which are 5 inch strips...
Lots of different rolls and buns out there...they can be fun! I am doing a quilt with a jelly roll and it's turning out beautifully. Moda fabric, Nothern Solitude is what I am using and making a pattern called "Split Decision". I will post when I am finished with it.
Have fun!
