Here's what I did to customize my IKEA Detolfs to get the most bang for my buck! Shave the sides and put two (2) of them together - instant custom glass display case for around $140 each! Here's pictures of how I put it together: I sawed off the edge of the Detolf boards before putting them together: I drilled holes and used mending plates, bolts, nuts, and washers to hold the two pieces: Here's what the bottom side looks like: . . . . and now, [I'm] putting in the frame for the Detolf: Add the glass sides, doors, and top pieces! Top bolted together just like the bottom pieces: See how small the gap is now between the doors in the front? I can [now] barely stick my finger through, whereas I could fit my whole hand into the original frame [before]: Now all of my Detolfs stacked side by side in pairs: Here's a [photo] after I added all the mending plates to all my Detolfs and bolted down the Detolfs to the wall using shelf brackets: . . . . and now my display room today!
