Hi Matt thanks for this quick reaction.
I’m a Dutch guy living in Belgium and I know that many countries have their own rules handling packages so I only wanted to know which material to use to ship my charcoal drawings safely. You never know how they will handle your artwork and I want to prevent smudges (although I use fixative) or foldings. Also I want to know if you have to send your client some extra’s but I think your business card and a thank you card will be suficient…. Of course I will be happy to listen to your podcast about it on Monday. I haven’t send anything yet because I have to make proper photographs before posting it on eBay. But thanks and keep up the good work!
