My granddaughters lived with me when they were 4 and 5. I sewed with them on my lap. I controlled the foot pedal and let them help me put the fabric through and pull out pins. One got my rotary cutter when I wasn't looking and sliced my chair. Fortunately she didn't cut her finger off (small cut, but not serious). They also loved playing with my magnetic pin holders...I had to have two, one for each of them. The 5 year old turned 13 yesterday. Thanks for the memory.
