How'd You Do?

  • 18-22 correct: You're fluent in quilt speak. You probably use half of these unconsciously in normal conversation and confuse non-quilters constantly.

  • 10-17 correct: Solid grasp. You know your way around a pattern without needing a glossary open in another tab.

  • Under 10: You're still learning the language, and that's completely normal. Bookmark this page and it'll come naturally.

One More Test: Confess Your Stash

Now that you know the difference between a WIP, a UFO, and a PHD, be honest with yourself:

  • How many WIPs do you currently have going at once?

  • How many UFOs are hiding in a closet, a bin, or "somewhere in the sewing room" that you're not ready to talk about?

  • Pin this: Test Your Quilt Acronym Knowledge: How Many Do You Actually Know?Pin It

    Do you have a PHD? As in, a project that's been sitting at exactly 50% done for so long you've forgotten what it was supposed to become?

No judgment here. Every quilter has a UFO pile. The ones who say they don't are lying, or they just finished cleaning it out last week.
