Once I got to putting all of my Kreiniks in the box though, I realized I had a problem. Ummm... I ran out of room.
To give an idea of size, these two boxes are spread out between the arms of my stitching chair. At a rough guess (since I'm too lazy to measure and I just took them upstairs), the boxes are about 15" across, 17" high, and <2" deep.
***UPDATE: To answer one question about the boxes: these hold 108 spools. As for mine, neither is completely full, and I have a few random non-metallic spools (Silk Bella, Londonderry Linen, etc) in the second one.***
(This makes two posts in two days - but I'm not expecting this to be the norm anytime soon!)
