There seems to be an error in the cut sheet for the Weekend Remodel Storage Bed project. The headboard height on the cut sheet is 18in. However, in the ****** video and pg 70 of the July 2012 TOH magazine shows that the headboard is higher than the head of a kneeling man: more like 38in than 18in. Has anyone else found this error? Doe anyone have a suggestion for what this height really should be?
