Quilt it or Cake it?

This cake for my Mother in Law has no writing on it, because it is in celebration of her birthday and Mother's Day, both of which we didn't get to celebrate together.  Putting those sentiments on the cake was going to come out something like "Happy Birth Mother's Day" but that just didn't sound right.

The cake is carrot, with cream cheese Swiss meringue buttercream and decorated to honor one of her hobbies.  There are three colors of "fabric", two designs of each color, laid out in a diagonal pattern with a fondant button on top.
