Hancocks of Paducah has them and the description says 220 colors. Then people came back from quilt market saying there were new colors, 243 total!!!
So I was waiting and wondering if I'd be able to get my hands on a new one with ALL available colors. The Kaufman site says they'll have cards available in early June but I wasn't convinced I'd manage to snag one before they were out of stock, so I finally went and ordered one from The Fat Quarter Shop (Mainly because FQS price + shipping was the same as Hancock's base price).
Last month I ordered 6 half yards of various colors for my upcoming Wonky Star engagement quilt, and a couple of the colors were different than I thought they would be (especially Sienna). I'd browsed flickr for pictures - lots of people have the same issues so some people make an effort to post photos for accuracy, but I am still left with one fabric that doesn't go with any project I'll ever make. The stores near me only carry about 8-10 colors combined, so I wanted to be able to order online and know what I'm getting. I really want to be able to get rolling on it so I thought the color card was a better investment of just crossing my fingers and ordering fabric left and right until I found the right color match.
My FQS Kona card came with the supplemental page with 28 more
colors, which I wasn't expecting and am super grateful for. Although really since I have 214 + 28 I only have 242, but I think I'll live without sorting through them all figuring out which one is missing! I was going
to email them to suggest they update the description so people would
know they would get the extra colors with it, but now they are out of stock. :(
Anyway, I suggest that if you use much in the way of solids or have to order online, that it's a minimal investment overall to make to make sure you get what you want.
