When making a pattern template for a cloth doll, simply use a clear transparency sheet. Out line the pattern onto the sheet and then label the pattern (write on the rough side) using a slick writer pen found at most hobby stores. Cut the pattern out and add some two sided tape to hold the pattern to the fabric.
The transparency sheet patterns will last a long time. You can make many patterns with one package of sheets. When not using the pattern, store them in plastic baggies.
