I have been sewing all my life, and collecting fabric almost as long. I seldom turn down free fabric. It's hard to walk past a deal on batiks. Therefore, I am drowning in fabric at the moment.
Can having too much stuff interrupt creativity? You'll have to ask yourself if you have organized it into a usable form. Ask yourself if you like things tidy and put behind closed doors, or if you are stimulated by seeing the raw materials scattered around you. You'll have to decide for yourself how you best work.
I know, you are reading this to get an answer, but like so much of life, the answers really do lie within. Know yourself and know what you need. As for me, I need both hidden supplies, and scattered supplies. I like having a lot of fabric, but the care and feeding of it is time consuming and a challenge to finding just the right one for a project. It's why I like going to retreats, I only have a usable portion in front of me, and have to make do. It's what my grandmother did, she cut up old clothes and made do. She didn't have to worry about making too many choices as she used scraps. That's sewing, but when we consider the idea of creativity, it's different. We can all sew. What we want to do is come up with the Next Great Quilt.
When I make color choices, I pull out the that drawer of fabrics to choose. I don't go shopping anywhere but in the stash. I feel there must be a critical mass for supplies. Like goldilocks, it has to be just right. There has to be enough to choose from but not so much that you have no idea what you own. Only you know if there is too much and it's getting in your way, or if you need an outbuilding behind the house for storage!
This is a happy problem, isn't it?
