Hi...I have some in blue, like 4 yds plus a remnat, but the yellow I bought is more like bubbles, 3 sizes. It was on the same shelf, but doesn't say "quilters showcase" on the selvage.
The blue, like yours, does say that on the selvage. My Joann's had these on sale for $1.99 yard a few flyers ago, back in mid-march...same time as Coupon Commotion. I bought 4 yds ea. of 5 different showcase fabrics...pretty stuff for that price. I got yellow, white and lavendar in the bubbles, blue only in your print, and a pretty black/grey paisley. If you're interested in the yellow bubbles, I could spare you some...only bought it for my stash. PM me if you want some.
