I had splashed some watercolour onto a tile awhile ago and I have been making Christmas ornament cards lately so used Twistee. I used a #5 Pigma Micron pen in dark green and then did some of the 'background' lines in a #01 black pen. I did some shading with a graphite pencil and a paper blender. Pretty simple.
I bought a bottle of Pebeo drawing gum for a watercolour course I took and have most of it left over so decided to try some strings using this resist and then doing some watercolour splashes over them. This is the first. I used the end of a paint brush to apply it. I will try using a brush or whatever for some more tiles, meanwhile I have a few that I did with the brush end.
