I've never tried disposable pans, but I'd imagine they'd work. maybe someone else will know

I haven't had any problems. as soon as I take them out I can hear them separating from the pan. and they pop right out with in minutes. Never had to line the pan with anything.

Love it!

Great Idea. I took this a step further and made it a chime. (cake pan, muffin pan, & mini muffin pan) Middle bottom strand I added a heavy fishing sinker and hot glued jewel diamonds to it for extra sun sparkle. For the top I drilled extra holes and put ribbon through it for hanging purposes.

for the red/white & blue one, I just put several small circles as a weight.
