I did some marbling last week. Each time that I pull out my marbling gear, I try a wide range of patterns and techniques, but also I will focus on a couple techniques or patterns in an attempt to improve them by doing them over and over. As you can see from the first few pictures here, I did a bunch of free-form curls on stone patterns - with and without antique spots. (Looks simple, but in fact, I find the antique spots very difficult to apply well.) Actually, these are all basically stone patterns - the black one is the Italian Vein variation, and the last one is stones with a spanish wave.
Of course, some of these are available on Etsy at MyMarbledPapers.Etsy.com. I'll get some more of my new papers scanned and share them soon!
