Welcome to the Quilting Board!

24 Blocks posted one like it on my Facebook yesterday call it kaleidoscope and it was made from men's ties.
I agree with Holice. I used this book to make a Giant Dahlia quilt years ago. It was one of the first quilts I'd ever made! The instructions are very clear and the card stock templates hold up well. At least with it adapted for a tree skirt, you won't have to worry about the centers matching.
Success is getting what you want. Happiness is wanting what you get.
I don't like the colors in the one for sale, but have a gorgeous one done in yellows and blues. I think the overall look can be changed to look any way you wish by changing your color choices.
you might find a pattern from Marti Michell. i know she has the template for the giant dahlia. hope this helpt.
