Windows and curtains14:54
Encouraged by your lovely comments I wanted to show you some of my progress on the roombox today. :)
I found a plastic bar (how do you call it?) with a 2 mm wide slot, and thought I could make the bottom half of the window slide over the upper part, by slotting both in the plastic trim. Above you can see the first design.
I wasn't completely happy with the result, so for the large window I cut squares from a single piece of cardstock, and glued it to the clear plastic as a whole. It took a while, but with better results.
