I've known ladies who work full time who do like janRN.
You could also cut things out on a Saturday or Sunday and have the blocks ready to go for when you get off work and perhaps do only one block if that is all the time you have.
I'm in charge of charity quilts for our guild. I cut out blocks when I'm visiting my mom (250 miles away so I visit a week or two at a time) I do it while she is napping.
A lot of our members work full time so they pick up the bags of 2 -4 blocks that have directions included and then they bring them back when they are done. When I have enough blocks for a quilt those go in a bag for someone else to make a top. That comes back and I add backing, batting and binding and the next person completes it. Sometimes another person adds the binding. It is all little steps to completion.
Perhaps you could apply some of that for your own projects.
