Mushroom Lane - Library Die Set (set of 7)

I love Mushroom Lane products and I always want dies to go with my stamps because I don't like fussy cutting intricate pieces. Sadly, though, the dies I've bought for the Mushroom Lane stamps are too big. For example, in this set, the die that cuts out just the top of the mushroom either fits the top snugly, or it fits the bottom snugly, but there is no position in which it is even all around. I have found other dies in the ML line to be similar with the fit. Maybe there's something I'm misunderstanding but this isn't my first time with dies. I've used them for many years. I like them to fit evenly and close to the edge of what I'm cutting. I can't say these do.
