I tried to make an easy face mask for beginners so everyone could try it and this is what I came out with, easy stitch, no decrease or increase, just repeat.
sl st in the second ch from the hook and 29 next ch. Next 50 ch, 1sc in every ch, sl st in the rest of the ch. Fasten off.
From the first sc in the mask, join the yarn , ch1 and sc in every st. turn
ch1, sc in the back loop and every back loop stitch
repeat for 24 rows.
On the 24th row continue chaining 51. sl st back to where you started the chain and continue sl st til the other side where you will ch 51 again and back with sl st. fasten of at the mask edge.
