Congratulations! You've bought a limited edition print by Stephie Jones - now what? The best way to display your beach print is in a matted frame. I prefer a white mat and a white frame.
If you don't have the budget to splurge on custom framing, I recommend buying a square frame (with mat) from an arts and crafts store like A.C. Moore or Michaels. They routinely have frame sales and coupons, so you can frame your print giving it a professional look for a much lower price.
For a 12"x12" print from my Beach Daze Collection, I recommend a 14" frame with a built in mat, like this one from Amazon. If you purchased a set of 4 (some of my favorites), you can take advantage of a set of frames, like this. Sets of 4 display very well together in a horizontal line, or as part of a striking larger square format.
