I call those fabrics "running eighths", but I'm not sure where I heard it- I didn't make it up. (At least I don't think I did.)
I saw these same prints at our Walmart and they had them in blue and green, too. And they had yardage of some of the prints, too. They are very pretty! I put the green one in my cart, but then I was good and put it back.
I had got some like that at Joann's that had teal and brown prints, but I wasn't overly crazy about it. I ended up with a lot of waste that wasn't really very useable, like skinny strings and a couple prints I thought were ugly. (I made my teal and brown quilt that I posted in the pictures section out of those, plus some other stuff.) If I had gotten it at the price you did, I would have been a little happier about the wasted stuff- it was a lot more expensive at Joann's.
Have fun with it! Show us pictures of what you make!
