Good for you making a tremendous quilt with your orphan blocks. :-)
I, too, have a short attention span when it comes to finishing. Enter my guild with the idea of choosing 6 UFOs to finish in a year for those who wanted. We put the UFOs on a list and turned in the list and kept a copy. Every other month, a number is drawn and we are to finish that project and take it and share the progress before the next number is drawn. So far, I’ve finished 2 bindings. One quilt was started over 10 years ago! Somehow it helps to have an external expectation group to help me get things done! Crazy!
