Child’s Scarf: Approx. 6 3/4” wide x 48” long
Adult’s Scarf: Approx. 8 3/4” wide x 65” long

For the hats and scarves, I used all of 4 balls of yarn with not even a smidgen leftover.

Having a look at the photo, here is what I’ve come up with for tutorial :)

Adult Version:
With red, ch 28.
Dc in 3rd ch from hook and in each ch across. (26 dc)
Ch 2, turn. Dc in each dc across.
Switch to cream and work 4 rows.
Switch to denimstyle and work as long as like the scarf, remembering that you have 4 rows of cream and 2 rows of red to finish it off.
Make sense?

Child’s Version:
Looks like it’s 21 or 22 dc across instead of the 26.
2 rows of red.
3 rows of cream.
Use denimstyle to make it as long as you wish.
Note the difference in lengths for the adult vs child version.

Hope this is helpful!
