Boo, Creativity comes in all forms. You may not have designed this pattern but you did pick it. Out of all the patterns in the world you chose this one. Good choice. Out of all the fabrics in the world, you chose very specific ones. Great choices. And of all the settings around you chose to follow the pattern. Well, that was another creative choice.
I used to say I wasn't creative but I could "steal" really good ideas. I've come to realize that what you do with those ideas is a type of creativity! Trust me :!: You are very creative!
Anyway, what I'm trying to say is "Nice Quilt!" It's beautiful and I'm sure your niece loves her SBS from her Auntie!
