Today is DH's B day, of course i'm baking him a cake. I went to the store this weekend and bought all the stuff I needed, but I forgot piping bags. What can I use? I'm out of ziplock bags too, I don't know how this happened. Im pretty sure my mom used to use bags made out of wax paper, but I don't know how to fold them, so if anyone knows please tell me asap, or if you have any other ideas for what I can use let me know, thank you!!

I'm sure there are YouTube videoes if you need to see it done.

Found a visual for you too:
