This is another technique that I learnt at the workshop with Sherrill Kahn back in 2002!
The top sample I made today the other I found in her book and I must have made at the workshop or soon after! Pieces of masking tape have been randomly applied to the card stock before sponging and stamping textures onto the card. Then I took off the masking tape and painted in the spaces. Finally I used some Pearlescant ink to highlight the masking tape strips and add some dots. Not sure what to do with it now...just look at it I guess....LOL
