Easter is just around the corner and I've been really looking forward to using my Michael Strong Easter Egg stamp for cardmaking. It's such a clearly etched 'cloisonne' stamp that works perfectly for this batik application.
A smooth white cardstock was used for these, but yes, a white glossy works so nicely also; in fact they both work well! The result is always rewarding, playing with colours, blending your favourites etc.
I've recently added this technique to my list of Helium "how-to" articles. Writing these how-to's kind of explains one reason, why my blog posts have been quietly put to one side (but not forgotten), for a time too.
