On craigs list I found a wonderful red steel bunk bed for $80 including the mattresses. It is a twin on full. I will keep my eyes open for another one which will need to be a twin on twin.
I told my grand boys that I would take all 4 grand kids to my local home improvement center and let them each pick out the color for one wall;
When done I will paint their name on their wall with their hand print and then set up the beds. This should be fun.
Happy Veterans Day!
