I actually thought about whether or not 'saran wrap' was universal--it is plastic wrap that you can use to cover/store food. You can use any wrap you want as long as you don't mind the fact that it will stain.

I was going to tell you that if you like the warmth, cover the water while it steeps in the wrap to keep it warmer.

Hope it helps.....
By the way--Becca is having-dare I say- a great week. She is starting to walk without her crutches and is taking a couple classes at school. She has been out since Christmas so this is pretty cool. Only about 18 days left of school, but who is counting--(Can you tell I am a teacher!)
