My daughter ordered a set of building blocks while expecting her first child and I ran across this Ultimate Building Blocks set. The set is proportional so all the parts work together to build and extend structures. Gathering a variety of woods; poplar, willow, eucalyptus, walnut, cypress, oak, cedar, zebrawood, maple, bubinga and purpleheart, I proceeded on a ‘simple’ project. 239 blocks later this is what I produced. Least you think this is a quick down and dirty adventure here are some numbers that astounded me. 52 square feet of wood surface to sand stain and seal. The edges sanding alone was 415’ of round over and sanding. It took me almost 4 months of labor including the box. Zoe should have many hours of creating WhoVille over and over again. Yes it does weigh over 30 lbs hence the wheels on the box. The water based stains and sealer are all child safe of course.
