Whoever invented zip-top bags is a hero in my book! I use them for all around storage and they're handy for travel.
I thought, maybe, there would be ways to prolong its one-time use. Here's an idea:
Cut off the zipper part of the bag. Clean it with soap and hot water, and let it dry completely.
With this, we'll make a zip-top gift bag...TADA!
Measure the paper to match the size of the zip top (adding a quarter to half an inch margin).
Fold the paper in half and make a crease. Add some glue to close the paper's edges and attach the paper to the zip top.
See, it looks like a bag now. Allow the glue dry for several minutes.
And the craft stamps, ink pads, and watercolor!
