I would follow through with the original plan and make the lavenders. Then when she's ready again you can do this new project. Sometimes it's hard not to get side tracked with new additions and start changing plans but since you were already going for the recessives and this new guy is a completely different project not an upgrade, I would just follow through with the lavenders. It honestly doesn't matter either way though, there is always the next season so just make whatever you're more anxious to have
Beautiful new pick up, I love OD calico and plan to make some with Desert Ghost, congrats!
