I thought this a brilliant way to store my threads given my new studio is small. Right behind the door, the thread racks fit wonderfully with the door stop protecting them from being smashed. At the old house I just hammered a couple of nails directly into the wall and hung them up. This was good enough as they were in a position where they didn't get knocked. This time I got DH to drill right through them to make them secure. This worked for the first four you see at the bottom.
But he was not around when I opened the box with the rest of them in it. I also found a reel of high strength double sided tape. This stuff is really strong, it will take up to an 11 kilo load, far more than a few reels of thread. I carefully measured where it was going and made sure there was a pencil wide gap between it and the one below. Lined it up very carefully before pushing it once into place.
Can you spot the deliberate mistake? And if you have any idea how I get it off without removing the plaster, let me know.
