I have sewn for 10+ hrs a day for several years.
when my youngest son was in 3rd grade( he is now almost 17)
for mothers day he made me a card and drew me sitting at my machines,table and all behind the open workroom door.
We had am embroidery business at the time!
At first it made me feel bad that this was the only way he saw me, but then realized (that with his autism) he felt secure in knowing where I was and I was a constant there!
