I used fleece for my toddler snood but jersey fabrics and other knit type fabrics work great and best part you don’t need separate lining so chose something soft.
Cut a rectangle 14×20 inch. Your stretch should be going along the 20 inch length.
Fold long sides together with right side of fabric in middle. Sew along that seam.
Next turn your tube out. Now fold up one short (unsewn) edge to meet another again so right sides face. Sew the two edges together but remember to leave a gap for turning. Try locate your gap close to the sewn seam that way it’ll be hidden inside when worn .
Turn out through your gap. I folded my snood so the long seam when worn will be inside rather than at bottom but it’s up to you what is easier. Hand stitch the gap closed using whip stitch.
Place on toddler and enjoy the silence because they are no longer saying I’mmmmmm cooooold!!!!
This is a great size for babies too! To make bigger to older children and adults add approx 5 inches.
