I agree with
@MySmallWorldof4 . Places like Michael's have some lovely boxes, and the merchandise keeps rotating, so take your time looking for just the right one. (You can look online, but I prefer looking in one of their stores, because sometimes things look different in person.)
You can also decorate a plain box or basket (either from Michael's or elsewhere), if you feel like trying that. I'm not all that artistic either, but sometimes just small embellishments added to a plain or printed background color can be really nice. Even a a complementary colored ribbon can make your box look special.
Aw heck, what do I know? Save yourself some time and ask our resident artistic expert, Figgy!!!
