I kept track of the size this way for YEARS.I always chose a nail polish color for each. example :red for 18, blue -16,Green for 14, yellow 12, orange 11. Purple was saved but never used. Just bought the cheapest nail polish at the drug store.Dip them then let dry on your pin cushion.
Of course after I became older and more senile I wrote this chart down and kept it close to machine.Since I used mostly 14 green meant GO...
Then I used the empty TIC-Tac boxes to keep the used ones.When I had time I would re-sand the edges and they were like new again. Just an idea that worked for over 50 years..Hope it helps you. Stella
