I am doing a on-line course with Glenda Waterworth it is week 1 and is resist techniques.The blue one is done by inking a glossy card in a pale colour stamp image using versamark going over the top with a contrasting colour rub over with kitchen roll and the embossed bit will show though the lighter colour.The multi coloured one was done the same but I went over with a multi colouered ink pad it is easier if you use a brayer.The brown one is done by colouring a piece of glossy card with several colours then stamp image with versamark and emboss with clear embossing powder then go over with a darker colour rub off excess and the image will pop out in different colour it is called the Jacob Coat Technique.
