I love my new 60mm Olfa rotary cutter. I don't know why I thought I was using the largest size when it was the 45mm one that has carried me through the last few years. I never noticed I had lost the bigger one .
Scraps in a basket might be worth re-visiting for a small Rooflines project.
A green Olfa mat is best. The blades do not dull as quickly with this mat. Again, a recent observation after my class in December in which I was going through blades every few hours and not necessarily secondary to poor technique.
Two healthy adults drive each other crazy inside the house in the month of January. Good thing I remembered that going to the coffee shop was an option today.
Some random thoughts for you on a rainy 60 degree January day here in Michigan. :)
