I am assuming that you are referring to the Border Creek Station Stash Buster Challenge.I have given it a try several years in a row, I don't do well with the make one blocks a week or even two concept. I make one or two and cant stop, so I just dive in and work on the quilt using their blocks which are pretty easy. For me the lure of a prize at the end or the chance of a prize is not motivating enough for me. I just like having a moderately simple block at hand and making a quilt top using what is in my stash. The one from several years a go I finished in about two months and it became a friendship quilt for a woman who was in her final days of life. Friends filled a block with scriptures of encouragement and their name. For that stash buster, I was glad I hurried ahead and finished early. Last year's quilt top is finished but is now a lonely UFO. No motivation to layer and quilt it because it is just to big!
I've not started this year's challenge because I have so many other irons in the fire so to speak.
Try it, they are fun easy and I found the directions good. Enjoy. And show your results here!
