Nope, sell them as knockdown, already painted, kits. You'll appeal to a broader audience and be able to sell them for more money. Sure, it'll cost more to paint them or use decals, but you'll make a profit on that extra cost and have additional sales to boot.
Hello! Just came across your post Was wondering if you had detailed plans for the bunk bed? Definitely interested in purchasing if so. Please let me know would like to have this made for my son's birthday in October so need to find someone to build it. Also, is this for 2 twin mattresses? Thanks so much! Looking forward to hearing from you
