I am not going to lie and say this was an easy stamp to mask. The 'wishing you' part is kind of connected to the circle that I wanted to mask out. I stamped on a scrap paper, then carefully cut out the circle. For the black words, I inked the stamp in black and then rubbed as much of the ink as I could off of the circle with a tissue, before fitting the cut-out circle over it. I figured by putting the mask right on the stamp, I would have a better chance of getting perfect placement. The ink that was left on the circle made the scrap stick. Then I positioned the hole in the scrap paper over that stamp and re-stamped in bright pink.
The stamp is from the Tag You're It ONE set.
It's not perfect, but I love the effect so I played it up with some teal and pink. See my blog for more details.
