Are you gifting in person or mailing? I’ve mailed two paintings I’ve sold recently unframed. I cut cardboard to size, taped the artwork inside it and then put the lot in a Prime or other type bubble mailing envelope. They arrived unharmed.
If you’re gifting in person, I would put it between the cardboard and then wrap that or put it in a shallow box and wrap.
Cardboard sheets that come inside wall calendars, a couple on each side; and then wrap in a layer of tissue paper before adding wrapping paper.
Better yet, mat it with a mat that comes from the art store. I hope there’s a little margin around the edges of your drawing so the necessary frame or mat overlap doesn’t cover any of the picture.
Cardboard. You can cut up a box. If you don’t have either and need to use something in the house try cutting up cereal boxes maybe make it double thick.
Nah, not cereal boxes. It’s a gift, and it’s not being mailed. Better to get some heavy card stock (poster board) and cut it to size. They have 22” x 28” sheets not only at art stores and Staples or Office Max but also at places like Target and even possibly Walgreen’s.
