Note from the designer: "I designed this mask because I wanted something to put Crafty Intensions Eastern Dragon pieces on.For the pieces I used her add on pattern, an I hook (5.50mm) (a 5mm for the horns) and 2 strands of yarn. The pieces fit perfectly for me, but you may need to play around with your hook size depending on your tension. I don’t know the yardage needed. I sewed the pieces on the same way you would on the dragon"
