I have oiled and cleaned two of my machines. One more to go. I love the quiet hum and once I get going on your blocks I forget to clean. I use the Baby lock for paperpiecing because it has the tread cutter. I like my old Berninia Record for piecing because I can move the needle. The featherweight has the perfect scant 1/4"foot too.
Back to heat wave. Really has everyone just dragging. We are only at mid 90's - I don't know how those who live where its over 110 deal with it. Today I refilled the 4'wide dog pool and just stood in it while filling. Ahhhh
