I think it's great you are thinking what you would like to have that will make your quilting more accessible for you. Having a list will make it so you can play whenever you feel like it.
I think you need at least the basics, cutting mat, long ruler, scissors, seam ripper, pin cushion and thread. Maybe a few books or magazines or patterns that are favorites that will inspire you. Your Iron and Ironing Board. Precuts are always good or scraps. Do you like to add a constant fabrics to go with them. I use lots of white. So, I would need my bolt of white fabric. Think about what you like and enjoy working with. Otherwise, inevitably, the things you need most will be out of reach.
Can you re-purpose a piece of furniture to hide your goodies when not in use?
Storage doesn't have to be expensive. Do you have an baskets you can repurpose? Or, I picked up baskets from the Dollar Store. They have great selection in lots of different useable sizes.
What about one of those cute little 3 stand carts from Walmart. I picked up one that sits next to my sewing machine. It is handy. I use the top shelf for my quilting do-dads and the bottom 2 hold triangle scraps and the one under that has Hunter Star Blocks precut that need to be pieced and a longer term project that holds precut kaleidoscope blocks that need to be pieced. You of course can store whatever is handy for you. I think I paid $25 for it.
Love this little cart. So handy. And, on wheels.
Love my organizer from Michaels. It rotates.
Repurposed little stand with Dollar Store Baskets. So handy for those strings or scraps.
Repurposed single chest of drawers. Or any repurposed piece of furniture. It could also be a nightstand which I also have in my sewing room.
Do you have any Desk organizers that can be repurposed. I saw someone else on her (Zoezee, I think.) I was able to pick up one for $10 with a coupon at Michaels. And, score, it rotates. Love it!! handy.
Here's so photos to get you thinking outside the box.
