I try to dust and vacuum after I finish each project. Usually I try to vacuum just before I get ready to put my binding on my quilt as its always dragging on the floor and will pick up every stray thread I threw on the carpet. I put all the fabrics I used on that project away or into the scrap bin and then pull out my next project. I sometimes need to dust more often during the project as my sewing room is in the basement. After cleaning though I feel like I did accomplish something as it looks all nice a new to me again..............CLEAN.
