Welcome from Texas! Right off hand it doesn't ring a bell...but, do you recall if it was recently, like a newer magazine?? That can help for a search...I sometimes will just go to google search, type in some key words, such as quilt magazine featuring paper pieced scrappy Christmas tree, then off to your left side of the screen, hit the image button instead of everything button. That way it will bring up pictures, and is easier to find, sometimes it actually will work...
Good luck,
Kif
