You have the support of the members of the quiltingboard. What can go wrong.
I was going to suggest you 'don't make anything'.
Take your machine, thread and scizzors to the radio or tv room. Out of and away from your sewing room. Take some scraps, cut the common size squares (3 1/2?) and start seaming them into a jelly roll. You never have to do anything with the jelly roll if you don't want to but the act of sewing may get your blood flowing.
If you do decide on a pattern maybe just take one section at a time to the radio/tv room and sew it. Ie: cut all the squares. Clean up. Seam the squares. Clean up. Press the seams. Clean up. Maybe a simple 9 patch. Make one square. Clean up and quit for the day. If you bite off small pieces and don't look at the finish line until you get there it will not be as overwhelming.
The Barjello is the most beautiful thing (next to the Cathedral Window) ! It looks very complicated and beginners say it isn't. I am going to study that pattern and someday I am going to make one!
WE CAN DO THIS! We have a very strong support group to help us and we don't have to do it alone!
The best to you. You can do this! You have already reached out and many times that is the hardest part.
We are with you.
