Potted Plants?

I'm still making leaves and looking for something to "plant" them in. Here are a few things I gathered up this morning...

I found this cardboard packaging that might work too?

I'm wondering what to use to hold the leaves in the pot? Clay? Florist foam?
What do you use for potting soil? Dried coffee grounds? Painted sand?

I hope to have at least one plant finished today? These leaves are for a bromeliad I'm working on...

It's so cold here today! I'm staying inside and dreaming of a stroll through Linda's tropical garden!

Thanks Linda! I love visiting your garden!

Back to the masking tape and wire with a gorgeous photo on my desktop for inspiration!
