I'm posting the results of an experiment with gel pens that was driven by this week's SSS Monday blog challenge which is "rock the techniques."
Using the pens, I wrote directly on the rubber of small sections of various stamps and pressed them on to the tag. Then I filled in the blank background areas with distress ink. I was able to capture detail with accuracy and color changes were a snap, thanks to the small pen tips and slow drying time.
Would I use this technique again? Definitely, but just for small bits and only after planning for potential smearing when other inks are applied on top. My gel pens aren't waterproof/permanent but that can be an asset with other techniques (see previous post).
