We built this bookshelf/toybox for our cousin's daughter - as a 1st birthday present. Overall, the project only took a weekend (including staining and waxing), and the cuts and assembly are pretty straight forward.
We wanted it to be larger than the one in the plans, so it took some time to figure out the dimensions before we started cutting. There was a bit of, "What do you think of this height?" and, "Is this too wide?"
My husband and I have built quite a few projects together so this one was fairly low on the difficulty scale. As long as you are comfortable with a mitre saw, you can do it. The kreg jig made it easier to drill pocket holes, but even with only different-sized drill bits and a steady hand you can make them.
This is one of my favourite builds - maybe because it was a gift for the sweetest little girl. Plus others have shown interest in it, so I might just have to start a side business!
