I am taking several on line classes at the moment - yeah overlapping in time - about working in series and when something like this happens, the subject pops up everywhere. Even in Pam's class - which is actually not on working in series, a series developed :-) Here are some starting points for tree quilts.
At the moment they are only pinned or glued, so maybe I will make some changes to them. And no doubt more will follow :-). All tops are 12"x12".
