Here is one way to place your mums on your Texas backer. It takes 12 – 4″-8 layer mums and 5 – 3″-9 layer mums.
The blue circles are 4″ mums and the red circles are 3″ mums.
The red triangles are 3″ mums taken apart – use 3 or 4 petal layers, fold and form to cover space as needed. You can spread petals out where needed or trim petals where needed to keep the Texas shape recognizable.

What size shape are you using? Do you have a printable template of the shape your referencing? Thanks, (on a time crunch)
