I have to build a bunk bed set for my grand kids. There is no question it won't be hard to surpass the quality of materials used in all but the more expensive sets. My question(s) is this. Where are good sources for bed hardware and also a good source for plans. Most likely I will end up customizing an existing plan. My daughter-in law has a firm idea what she wants. Any and all advice is welcome and I thank you in advance.
