April your layout and suggested card are really lovely. Masks are so versatile I use them all the time, and there are lots available for free on the internet – I haven’t done much with making my own yet, I always seem to need one in a hurry and don’t have time to make my own!
This is a card I did for my Brother-in-law. The window on the front was cut-out after I printed it to show the picture on the inside. The elements and the mask all come from a Studio Manu set called Grandma’s Reading Room, and I did the calendar with Keith’s birthday marked on it.
