Over on threadbias, they have their own method of dealing with finishes. You sign up for a 3 month club, list a selection of unfinished projects you want to get finished. The group is divided into smaller groups of about 6-7 members each, Then here is the good bit
, every one in your group has to send you a fq for each finish you achieve (although it was limited to a max of 2 fqs). If you don't finish anything you don't get anything, but you still have to send fq's to those that have finished a project or two. You can specify type or colour of fq's if you wish. I joined in for a year - four times, and started off specifying neutrals, and then switched to blues - got some great additions to my stash that way
