I often see fabric shops and can’t resist going in to ‘just have a look’. My husband has learnt that this very rarely happens and I often come out with at least two different projects in my shopping bag. I love to walk the aisles just looking at the fabric choices and thinking about what I could make, who would good in that pattern and just feeling the different weights of fabric.
If I am searching for the perfect fabric for a particular pattern I take a photo of the reverse of the pattern envelope so that I always have the exact quantities there in my hand. That way I don’t ‘over buy’ (is that even possible with fabric?).
