1) I've learned to not overcommit.
2) To clean up between projects.
3) To try to finish a project before starting a new one because I rarely go back and finish once I quit something for awhile. (Too hard to find all my fabric and pieces again.)
4) To keep my seam ripper off the bed of my machine because I keep sending it onto the floor behind my table as I sew!
5) To hide my good scissors during popsicle season (because my kids use them to cut the top of the plastic off!)
Oh... and to not feel guilty when I don't make a quilt for someone who asks me for one!
