Mylar Sheets
Mylar sheets, when fed through their reader, have the blacked-out squares read electronically, signaling which needle should be placed in working position.
- If your machine uses a mylar sheet reader, you can also purchase these pre-marked, or you can mark your own. You should lightly mark in the design before you fill the spaces in completely.
- In the case of the mylar sheet, the squares that are marked are the equivalent of the ones that are punched for the punch card machines.
