If you are making artwork incorporating butterflies and need the butterfly or moth positioned with a gentle angle to the wings, this board is the way to go! NEW and improved, based on customer feedback we have redesigned this spreading board with a greater angle (about 25 degrees) which will give the wings a more dramatic and in-flight look! This is the GOLD standard, the highest quality spreading board on the market, it will last 100yrs and can be passed down to the next generation of bug enthusiasts! This one size fits almost ALL needs and sizes of butterflies, even the Birdwing butterflies!
