Here's my index card art for Monday through today, Wednesday July 25 (aka challenge cards #53-55). I enjoy working in small series; the work seems to go much quicker and I can switch up ideas immediately after three or four cards are completed with a single theme or technique.
I felt the backgrounds of these cards were already interesting and detailed so I finished them off with the simple addition of foreign postage. I used to collect postage stamps for use in my artwork but once again, I haven't even looked through the collection in years. I [re]discovered all sorts of cool images!
