Morning. I tried colouring on some pearlised card stock this week to make this pretty DL card. Due to the coating it didn't blend too well I found the alcohol ink puddled for a few seconds before evaporating. So I tended to use my lightest colour first then added my darkest then mid tone before going back over with the light. I normally work light to dark or vice versa. Still I was quite happy with the finished result.
