You know that you are a quilter when you are constantly picking loose threads off your clothes and find them on the floor in your bathroom, and on the sofa, etc. The best ones are when I have to pick loose threads off my DH. LOL.

You know you are a quilter when you stand in line at the supermarket and talk to others in line about the fact that their blouse fabric would be great in a quilt!
You know you are a quilter when every time your phone rings, it is a friend calling to tell you which garage sales have fabric for sale, you find yourself buying clothes that you know will be great in a quilt when you tire of wearing them, you can tell what a fabric is made from just by touching it, and you are a real quilter if you understand that "Done is better than perfect" is a true statement of purpose.
You are a true quilter when you spend two hours on a road trip to deliver Christmas presents, furiously sewing the binding down on one of the quilts to be gifted when you get there!

Look at the tile designs in a restaurant bathroom and think about what a nice quilt design it is!

Being at work dreaming of your next quilt project.

Have quilters magazines everywhere in house!
Snips of fabrics laying in a pattern formation on your coffee table!
Pins still on your shirts

You may be a quilter if you go to the butcher and ask for a quarter yard of ground beef instead of a quarter pound of ground beef.

Are covered with threads, your DH picks them off your clothes, and you thank him and say:

"Those are my heart strings!"

or

"I come with strings attached!"

I just caught myself trying to do math and kept subtracting .5. Yeah I was thinking in terms of finished and unfinished blocks. Lol. Doesn't work so well with grocery shopping lol.

when you sit in the get healthier you program as the local hospital and doodle new quilting designs with the pencil and paper that they gave you to take notes [happened just this morning ]

when your out back with the dogs on a gloomy day and look up in the sky and see a piece of fabric that you have in your stash its a little more grayish then in the photo
