Lucky red packets

It's Chinese New Year (or Lunar New Year to be politically correct). I've received some lei si (aka lucky red envelopes/packets), and I've realised some of them have very cool designs. Here are some random images of said red envelopes I found on the internet.

I have chucked out some really nice ones in the past. I regret that now. I'd like to start a collection of them, turn them into a collage and hang it on my wall. That would be pretty and meaningful to me. I'm not really good at getting in touch with my creative side. I think I'm a creative person, but the pragmatic side of me doesn't make room for creativity. This is probably the one of the few creative things I'd like to do.
