I need a sturdy damask stencils for a cake tier that will be at least 6-7 inches tall. Most of the stencils i saw and have are very very flimsy and not more than 4 inches in height.
Do you have any type of cutting machine such as a Cricut or Silhouette? You can cut pretty thick sheet of acetate in them and it makes great stencils.
Try the Evil Cake Genius. Their stencils are usually 6" high and the quality is great.
