Earlier in the year I whipped up an ice cream pint cozy using the pattern in Amy Singer's Knit Wits for my hubby's grandma. I used Cascade Fixation which a has elastic in it.
I bought a special spoon fo rher to use. I was hoping to find a plastic handled one that would match one of the yarn colors but I didn't get that lucky. Anywhoodle, she loved the gift.
i really like your booglass. it's nice and colorful!
