When I have multiple projects going at the same time I try to tie all the pieces of each one together and put them in a box or tote near my sewing desk. I also try to put other 'stuff' away or at least out of my sight so I don't get distracted and begin another project. It works pretty good but I have to admit there are a few projects that have been in the box for quite some time because something new always comes up and takes precedence. May in Jersey
