Due to the size of the stencils when we post these out these will be loosely folded. This is how they arrived to us and this will not effect the stencil adversely in any way. Trish McKinney's 12" x 24" Branches Mask features an entwined thicket of branches. Use it when you want to go large in your artwork and as an integrating stencil when combined with other masks designed by Trish. Product Details: 12" x 24". 7 mil mylar is thick enough to be durable, yet thin enough for a seamless look in your art. Made in the USA.
