You post your cards on various specific sites and others comment, critique, like and trade. You ask to trade card for cards and although you pick a card you like; sometimes when you have it in your hands you actually appreciate it even more. You are able to feel the texture, see a sparkle and if it was a specifically asked for custom card you feel the love put in to it. I have a binder full of beautiful cards.
We have all had penpals and they both still do but now they are able to express talents they have or find and experiment in areas they were not comfortable in as they make things they didn't know they could do. To hear my childs enthusiasm after they are pleased with having drawn something they thought they couldn't is my reward.
This is where my happiness is.
