I'm starting to participate in my first swaps, and I've realized (by looking at photos on Flickr) that it's very common practice to send "extras" along with your swap package. Me, I would normally just send whatever the swap said to send, not wanting to put the person receiving my package on the defensive for not having provided an extra themselves. But, now that I see this as a pretty common practice, I feel compelled to include extras in my swap packages (a) because it seems like a nice thing to do and (b) I don't want to get a negative reputation for being stingy.
So, now that I am on the "Swap Extras" bandwagon, I have no idea what kind of "extras" to provide, especially swap and quilting veterans. Any good ideas out there for a swap newbie like me?
