(Used this mostly as inspiration for Ellie's 1st birthday banner.) Didn't use paint-chips. (Seriously people, that's basically stealing.) Cut hearts with Cricut (about 2.5"). Cut "Happy Birthday" w/ Cricut (1.5"). Glued letters to hearts, punched holes in the tops and strung coordinating ribbon through to hang. Took two hours, off and on.
Looks like paint samples (explains the nice gradient effect) cut with a butterfly stamp cutter and pasted on in the shape of a heart. Challenging but could turn out well!! (And, as always, when you use a canvas, you can hang it on an adhesive wall clip on the stone walls of your res hall room.)
