Was it a masking tape alpha? From Amy Martin? That's the one that sticks out in my brain, but I think she retired it? I'm on the hunt!
I was just about to come in with Val's that I saw last Wednesday but can't find it anymore? Found it https://the-lilypad.com/store/product.php?productid=2077&cat=130&page=1
I love that alpha and need to go shopping myself. Every time I see it I always think I need to scrap a page to use it on.
