If it needs to quilt to a 5" square, you need 5.5" to start with. Check the directions again.
Edited: - I just looked at the directions for the first month of the Craftsy 2016 Free BOM Garden Charms. You're cutting squares for an hourglass block. This uses the same math as for side setting triangles, adding 1.25" to the finished size. You will wind up with 4" hourglass blocks, finished size.
