I found a large wreath box at The Container Store for super cheap during the holidays and bought 3 to store all of our wreaths. They are large enough to fit one big guy or two medium sized wreaths. I thought about going plastic but could never find one that was big enough and was worth the price.
These were easy to put together but one negative is that they aren't see through so they were in need of labels.
No Problem! BHG has downloadable labels that I love so I printed them out, self laminated them with some clear packing tape, and used pocket brads to attach them to the boxes. Now they are neatly tucked away in the attic and ready for next season!
