The sewing course said to get a rotary cutter and mat. I had one at some point and never really used it so I donated it. I bought a second one because I'm wasteful like that. I guess I never realized what to use it for before. It made cutting out napkins quick and accurate. Now they will all be the same size!
I don't like how most cloth napkins are not absorbent at all so I did one size a gauzy material just to see if it works better. I have a feeling it's not going to hold up great but only time will tell.
