Yes, Toni, you can join in at any time on the BOMs! Do the ones you want to try, save some for later...make them at your own pace! If one looks too scary to try now, go on to the next one. Maybe in a few months you'll want to come back to that other one.
And Chele... they don't have to coordinate! Go wild!!! I KNOW you can do that! LOL
:D
