Tote bag treat holder. There's a video, but no template. I might try making it in two parts (plus handles). Draw the bottom of the bag, then draw a "rim" around it. Notch the rim so that the little flaps fold up. Fold the body of the bag around the base, gluing the inside of the body to the little flaps. (You can get a different look if the strap opens out into a single layer where you attach it, but it won't be as strong.)
You could do this with any accent colour for a zing. Also you could change the EF to something equally simple that you have on hand. I would probably have the butterfly partially off the music square, at the top, right corner.
Great way to use scraps! Trace actual puzzle pieces (or print and cut from internet) onto small pieces of scrap paper to create this simple DIY valentines card. Stamp, print or write your personal sentiment to your loved one.
