I use "Kabnet Wax" made by Dixie, it is unwaxed deli paper. It sews well and goes through the printer. I bought mine at BJ's I'm sure they would have it at Sams club and/or Costco also. It comes in a package of 2 boxes and each box has 500 sheets in it. total you get 1,000 papers for about $12.00 The papers are 12"X10 3/4". Although I got mine about 2 years ago , they should still have it. Great stuff!
