This was one of my first woodworking projects I completed with limited help from my handy husband. And the first time I used a jigsaw (to cut out the handles). I used mostly scrap MDF we had leftover from other projects - only purchasing one additional sheet of MDF for around $12. The MDF worked ok, but I did have some trouble with splitting when screwing it all together and screwing the castors on. Used our Kreg Jig where it made sense.
As a beginner, this project took me somewhere in the neighborhood of 16 hours over the span of a couple weeks. Cost was approximately $50 - including the MDF (but I used mostly scrap we had on hand), spray primer and paint, castors, and "Library" decal.
