Morning. Not so much to say about the size of my quilting room but the use of the vertical space in the quilting room is really important and often forgotten.
When you are thinking about "which" to move into, do consider the up space. And remember that a goodly number of pieces of furniture, etc. can be stacked. Voila, lots more room. And there are new hangers out there that can be used without putting holes in walls. And sometimes husbands can be convinced into making heavy duty, large, vertical storage that will do just exactly what you need to have storage do.
I have two: one for my big desk, three printers, paper storage, computer books, etc., etc. That one goes to the 8' ceiling in his office. The other, similar measurements, is in my sewing room. Two sewing machines and their cabinets (I regularly use these so the first vertical shelf is placed so I do not hit my head on it) sit under it and all my odd sewing supplies go on the shelf above in plastic bins. To the ceiling also.
None of this is beautiful but very functional. And you can hang lights, notes, works in progress, etc. off the husband created vertical space.
Enjoy figuring out your new sewing room. Happiness is enough space. I wish it for you.
