I saw t squares in Staples last week. I was picking up some vellum paper for foundation piecing (recommended by an artist/quilter friend). Best thing was- I thought it had 25 sheets and when I read the patterns I needed 28- looked at the package, it had 50 sheets. Cool! I can allow for learning curve errors.
I keep a piece of batting handy for a coaster by my laptop for my drink and another piece to wipe my machine off after I clean and oil.
