I am also a barefoot (or at the least with socks on) sewer. But
always wear slippers indoors and slip one off for sewing.
Being diabetic my Dr. drums it into my head that I must NEVER
be without shoes even indoors because if I got cut, stepped on
a pin/needle or hurt my feet that it could be much more harmful
to me.
If your not diabetic (or are familiar about diabetes) if we get cut
or injured it is very likely going to take longer to heal, and if you
have neuropathy (also known as nerve damage) to any part of
your feet (and toes) than if you got injured you wouldn't feel it.
As for me I DO have a small amount of neuropathy in my toes.
