How can I store all my craft floristry things?

I'd remove everything in the room. Get stacking bins and sort things into labeled bins as you bring things back piece by piece - don't forget to throw away unused or worn things.

Hi Flower!

Oh goodness. I think a lot of us have been where you are at some point, I know I have! Sal is correct about getting everything out of that room and doing a good, old fashioned sort and purge, that is definitely the first step. However, I'm not a huge fan of stacking bins because it seems all I do is stack and unstack bins whenever I need something.

I am a huge fan of utilizing vertical space as well; it's shocking how much more you can store by using your wall spaces!

Also, as you know silk flowers need a place where they aren't crushed out of shape to be stored, and knowing what you have ensures you don't buy unnecessary duplicates.

I would suggest creating a custom solution for your flowers to hang on the wall. Start with a sheet of 6mm MDF. That's a large sheet so you may want to have your DIY store cut it in half for you, and save the other half for another project (or who knows, perhaps you have that many flowers. If so, just carry on with the full sheet if you have the space). Drill 6mm holes around 50mm apart across the entire piece. Create a frame from 18mm plywood that is around 200mm deep, and has a second strip of plywood about 25mm inset 7mm from the top that will allow the mdf to sit flush with the top of the frame. Just screw it all together, fill the screw holes and joint gaps with putty and paint if you like (matching your wall color would help it to recede visually). Then mount to your wall with a french cleat. You can then just pop the stems through the holes and the flowers will sit on the wall without being pressed out of shape and you can see exactly what you have.

For all your bits and pieces it looks like you already have several drawer units that you can customize with bins to keep things separated. Depending on the size of fabric pieces you have I have seen people use filing cabinets with the hanging file inserts use those with small dowels notched for the rails and drape the fabric over the dowels to keep it sorted.

If you use 2 drawer filing cabinets you can also put a piece of premade worktop on top of them using the cabinets to support it to have a great flat work space. You might even find a piece secondhand from a kitchen remodel to keep your costs down.

You can screw a couple hooks to your ceiling and hang lightweight chain from it about half a meter apart. cut dowels to that size and screw small hook eyes to the ends. Thread your ribbon spools onto the dowels, insert the hook eyes through the chain and drop a wide headed screw through the hole to keep it locked in. You could have multiple rods floor to ceiling and even hang baskets on the dowels holding more bits and pieces.

Pull everything out of that closet and install shelving the entire height of it so you aren't stacking boxes, you can just pull them off a shelf.

It's quite a lot of work redoing a work space like this but you can do it!
