Speaking of summer, my current stamp set from Raisin Boat (I subscribe to their program and get 2 stamps sets each month to play with. It's a cool program!) Sealed with a Kiss, is really a Valentine set, but it has this adorable mason jar with Monarch butterflies that I couldn't resist. (Monarch's = summer for me in case you didn't get that connection. LOL)
I stamped the mason jar and two butterflies on white cardstock and cut it out. After coloring (with Copics) I stamped the jar again on vellum and glued it over the top. It makes the butterflies look like they are inside the jar. I used gold metallic rub-on for the jar rim.
