Ooh! Don't worry about contributing until you're good and ready... but I'll looking forward to seeing what you've got!
I started my collection when I was about 8, got really into it in high school, and since then... well, it's sort of gotten out of control. I have to keep it on a leash. I do love my stamps.
Stamps are the best hobby... they cost nothing and weigh even less. They are tiny, tiny works of art. They are typically designed by three people: one to make the picture (which must commemorate something worth remembering or aspiring to), one to design the text and numbers, and one to design the border. Nice ones can be looked at hundreds of times without discovering the complexities. Czech and Japanese stamps are the best, but Hungary and Poland do a good job. The U.S.A. used to make great stamps. They make "cool" stamps now, but nothing compared to a few decades ago.
I want to do a bit more space travel, myself. Virgin Galactic! And RAK in the UAE is building a space port!
p.s. If you join or watch my community, I promise to post lots more space travel related stamp scans. I have a whole album of space stamps, and lots more loose space stamps that haven't made it into the album yet.
