Isn't this just the sweetest image? It's a rubber stamp from the UK company, Lili of the Valley.
I colored it with Copic Markers, added a computer-generated sentiment and a sweet gingham bow onto this custom card size (4"w x 4.25"h) with a top fold. I'm adding this card to a boxed set I'm making for a friend ...
...LOL, a friend who would be unhappy to find mice in her kitchen! I hope she likes the card anyway.
Update: Envelope technique
I confess I was dreading making an envelope for this odd shape, and I want to share with you an interesting technique to have a colored interior to match your cardstock, while leaving the exterior postal-friendly white.
I created a template on hot pink scrap paper, then went to my color copier (inkjet) and copied the template onto white cardstock, like this:
|They're actually the same size ... the photo distorts it,|
though my color registry is off on the copier. I like the lighter pink
for this card, so that's okay.
