I start out on a dry erase board . gives me the ability to change things easily . then I draw either a full scale or half scale on my drafting table . then some times I make templates out of thick poster board . I also use left over stick on floor squares to make small templates. like for sectional bowls . I have a set for 6 & 8 in bowls. each with 6 pcs to a row , 8 pcs to a row and 16 pcs to a row.
