I'm interested in solutions for this too. I'll start something and then get distracted by another project or like today I cut out several wool sweater mittens while watching a movie, sewed one pair and discovered that the pattern needed an extra inch added to the bottom to fit correctly. Now I don't want to sew the other pairs because I've lost the momentum. I do this alot, get excited about something, cut out the fabric, then lose interest.
Is there something we can take to keep our focus?
