I'm going to have a quilt of these little cuties for Mom by Christmas. (Or else, self! Or else!) I found the non-jelly-friendly block instructions HERE and they just happened to convert really well to jelly-measurements.
If anyone would like to know how to construct this and can't do it quickly from the link, please feel free to PM me! I just made the block on my 30 min lunch break + 15 min break as I worked on puzzling it out. It was friendly to little slips and mistakes, too.
(Jelly rolls features are Connecting Threads batiks and marble.)
