Finding inspiration in the most unlikely of places: When I went to see Saw 3 in the theater there was a flashback scene of the main character sitting on his son's bed (who had passed away). The first thing I noticed was the brick quilt on the bed in various blues and thought a denim version would be fantastic. Video games are also a major quilting inspiration. (...actually, thought of a game just now---Bayonetta---and remembered the main character's clothing color scheme and thought "That could work in a quilt". No joke.)
Checking literally any quilt out: Whenever I go someplace and they have a quilt up on display I go up to it to check it out. Last one was in a hospital and they had a quilt with a black background with neon colored compasses.
Looking at a store bought quilt and thinking you can do that and make it better: You have no idea how many times I pass by the bed and bath section at work and think I could make that myself...and I'm not even talking about the ones with the faux pieced quilt look.
Being able to name any quilt pattern without thinking: My boyfriend took me to a quilt shop I never been to and was able to tell him the names of each quilt they had showing.
Explaining quilt terms to your boyfriend: At same quilt shop I explained to him with a passion what "jellyrolls" and "fat quarters" were.
When asked what you want for your birthday you say you want to shop at a quilt shop: Which is why me and my boyfriend were there in the first place.
I won't get around to doing my taxes, but I will literally spend hours looking for fabrics I need for a project on the Internet: no joke.
When you're working on something non-quilting related it somehow has quilting involved in it: I've been doing my seed starting project. Instead of setting up in the closet like last year I bought a small wire shelf to put my plants on. Problem was I had disposable baking pans to put my plants into (they were cheap) and they would make this ungodly sound when I'd put them on the metal rack. Like clashing cymbals together. My solution was putting batting on top of each shelf to absorb the noise. Also have been using my ruler to help me make different widths of newspaper for my plant pots and seed tape.
