pinstrosity 

2. a Pinterest pin of great and often frightening size, force, or complexity. Pinterest may be more pinstrosity than not - a high percentage anyway. Recipes, sewing, crafting, home decorating, DIY projects - all are subject to posts from the experienced who overestimate the same skills in their followers.

"I am looking for an Easter treat idea that isn't such a pinstrosity."

When you attempt to make a project you got off Pinterest and it turns out awful.
"I decoupaged a frame, but it turned out to be a Pinstrocity. Nailed it!"
