I liked the technique so much that I created by nephew's birthday card using it and a retired stamp set 'Very Puny'. The cows were chosen as they live on a dairy farm. Below you can see a close-up shot of the glitter window that I made as the feature window.
The 'Bandanna Technique' I picked up from Claire's website and one of the things I learnt from doing this techniques is the best white gel pen to use is the one I bought from Stampin' Up! which is a 'Uni-ball Signo broad' pen - pigment ink. I have two others, another Signo pen but that one does not indicate it is 'pigment' ink, although it runs better than my other white gel pen which is a 'Hybrid' one.
The technique is very easy. I stamped on Whisper White card stamps from the Polka Dot Punches (SAB promotion) using Staz On black ink. I then sponged or brayered over the Pumpkin Pie ink (I showed both ways at my workshop) and then highlighted areas of the design with my white gel pen (pigment ink one!). One of the ladies had a go using Wild Wasabi and she really noticed the impact that the white gel pen gave to the design.
