This card is a variation of another card I made earlier this year for a Black and White only swap. I changed it so I would be using Basic Black ink instead of Whisper White. I couldn't have the make n' take participants waiting for four hours for their ink to dry ;-). The background is done using the Spritzer tool (AKA snot sucker). There are a couple of different stamp sets you could use for the lines and the heart. the heart is embossed white. I think the workshop participants enjoyed making it. It has a few different techniques, and is not too time consuming.
PS. My apologies about the watermark. It seems to have faded AND grown since I last used it. I will try and make a new, smaller one soon.
