I signed up for the Ricky Tims Quilt Luminarium, think originally it was going to be in March or maybe May. Anyway, one of the first things that got cancelled due to Covid. It's been rescheduled twice now, I think we are currently hoping to be able to do it in February 2021...
While maybe not my favorite to make, my favorite to use are Snowball blocks. I've made more than probably any other block, usually combined with alternating blocks or just as little sashing squares, or as an all-Snowball quick baby quilt I've done it more than once.
Otherwise, Log Cabins and variations are probably my most repeated block.
