Derwent Inktense on Fabric

This weekend I tried painting with Derwent Inktense on fabric.

I started by cutting out an ACEO sized piece of denim from an old pair of jeans. ACEOs measure 2.5 x 3.5 inches, and you can read more about these fascinating collectible paintings here.

According to Derwent, intense pencils and blocks are washable at 30 degrees celcius proving they have been completely dissolved, so it is important to make sure that the fabric is thoroughly damp before using the pencils. 

So to begin with I used a flat brush and clean water to dampen the whole piece of denim to the point where it was most definitely damp, but not soaking wet.

Inktense pencils work really really well on the damp denim - much better than I have ever found them to work on paper. The colours were very bright.

With the inktense blocks I picked up paint from the block with a wet brush, and these also worked well but were not as vibrant and did not spread very far.


Next stage was to let the painting dry - seemed to take an inordinate amount of time! I'd forgotten quite how long it takes denim to dry, but I was patient and let it dry naturally. You can see that the colours dried into much more muted tones.




Once dry I added some definition using the inktense blocks, picking paint up from the block with a wet brush and applying it to the now dry denim. This worked well as the colour did not spread as much on dry fabric, although it did still spread a little.




Next day the denim had completely dried, and again the whole painting was much more muted.




Now for the scary part - time for my little fishy to go for a swim!

According to Derwent, inktense is fully washable at 30 degrees celcius. I prepared a nice warm pond for him with washing powder (that took ages to dissolve at that temperature)...


And in he goes...


After 5 minutes of swishing, prodding, and a gentle rub, you can see that a little of the yellow has run, but otherwise the washing water is pretty much the same colour as before.



Here is is straight out of the bath, looking good I think! I made the mistake of squeezing him dry, which left him full of crinkles, so I thoroughly wet him again and left him to drip dry.




24 hours later he was quite dry and, disappointingly, quite faded.



I very much enjoyed this exercise, but have to conclude that inktense painting on denim is not durable enough to be wash-and-wearable.


I will be re-painting this fish with my inktense blocks, but this time I won't wash it!
