I have been having a play to show you the results. The first picture is of the standard gold german scrap.
Next is the same pieces after they have had the nail varnish remover treatment.
I then had a play to see what I could use to colour the scrap. I had some success embossing with coloured embossing powder but it didn't cover totally due to the embossing pad and powder not getting fully into all the little intricate bits - it did give a lovely distressed effect though.
Next I tried colouring with various different inks. I tried Distress pads, pigment pads and adirondack dye ink pads but they didn't work at all - then I used my beloved Stazon ink pads and they worked brilliantly.
This next picture shows all the German scrap I coloured using Stazon ink pads (I removed the gold with the nail varnish remover first so that I would get a true colour). The borders on the left hand side from top to bottom are coloured with Stazon Jet black, Forest Green, Pumpkin, Cotton white and Royal Purple. The wings on the right hand side from top to bottom are coloured with Stazon Blazing Red, Cherry Pink, Azure blue, Timber brown and Mustard.
I particularly love the Timber brown coloured one as it has come out a lovely bronze effect.
Just editing to add: Tina says they also colour in really well with peel off pens (or other permanent markers).
