It’s very important to properly document your finished artwork. You need high quality, high-res images (300 dpi) to keep on file for promotions, prints, and posterity. Always document your work before you sell it or put it into a show. This can be done through hiring a professional artwork photographer or taking it to a place to have a scan made (depending on the size and medium of the artwork). You can also document your own artwork if you have the right equipment. Taking iPhone photos of your work is sufficient for many things like show entries and social media, but it’s not usually good enough for making high quality reproductions.
You can purchase art packing supplies yourself and ship with any standard shipping company, or you can pay a professional art packer and shipper to do it for you. Remember that everything you send out represents your art business, so if you choose to pack and ship your work yourself, be sure to make it look clean and professional.
