Some time ago I solved the problem that all watch collectors face, where to store the watches safely and in a manner that they can be seen and easily retrieved to be worn.
My solution involves a clear plastic storage container, with lid. Capacity is 10L and approx. internal dimensions are 46.5cm x 30cm x 7cm deep.
They look like this:
and with the lid off:
here in the UK these are readily available and cost about £8.
Then you need some high density foam. This is not so easily found. I was lucky that in the town I live we have a community scrap store. Local businesses donate things which are then either given to local play schemes and / or sold very cheaply.
Now and again they get off cuts of foam which I pick up for a few £'s.
You just need a piece at least as big as the box
This piece was 3cm thick which works very well.
Then I cut out a piece to fit the box - 46.5 x 30cm.
I use a serrated kitchen knife for this. Once the blank piece is cut out, I mark the 24 (3 rows of 8) holes to be cut out.
The marking out is fiddly, especially if you don't want to get ink lines everywhere. I have a technique for this now (I'm on my tenth box!!).
