A bit of a design flaw
"If you want a lighter flower center than you overall flower color, it is difficult to achieve with this stencil set. It could be done, but you would most likely have some over lapping of the flower color onto the lighter center color because of the way the stencils are designed. Darker centers are no problem at all. The stencils work great and I do love the set, but i had to go with dark flower centers because of the way they are designed."
