The first time I used this particular tip that I'm about to share with you I thought my Mom was going to fall over from laughing at me. Not only did it work, it made the ladies at the cutting table quite happy.
You're shopping for fabric for a particular quilt. You need many different colors with many different yardages. You don't know what you want your borders or bindings to be yet so you're leaving these quick calculations until you hit the cutting table where you go back and forth on how much you should have them cut. This typically results in purchasing way too much fabric. At the dollar amount we're paying these days per yard, that's not really realistic. Sure, there's some fabrics you don't mind having in your stash but at the same time; not everything needs to be hanging around in your stash.
What I've started doing instead of just toting the pattern with me is taking blank address labels before my trip and writing on them the amount of yardage and the color. Or if I'm really oraganized I'll type them into a Word document and print them up. I can then stick my label onto the fabric and when I get up to the cutting counter there's no confusion on how much is needed from each bolt. My labels then stay right on the fabric so that when I go to make that particular project I know how much is there and what it's for.
I found this extremely helpful when pulling fabrics for an Art To Heart Reindeer Quilt. I had intended to make it right away. This was last winter and I still haven't gotten to it yet. I needed 3 different reds, 3 different greens, 3 different blues, browns, etc. My labels are still attached and when I finally do get the time to work on my quilt I won't have to wonder what colors were chosen for which parts.
