Yesterday I noticed that my rotary blade was feeling dull. Well it was not
really the blade which I had just cleaned (with WD40) but it was the fabric
which had been washed but not yet starched. As I was cutting the overlock
seams the fabric was getting stuck in the mat. Finally I gave up and used
my scissors. Now I know why my mat usually stays pretty clean when I cut
starched fabric but this sure made quite a mess.
Just thought I'd share my little experience. :-D
