This is something that I have been meaning to try for a while as it reminded me of Ma(r)king time and the punching hole technique.
I made my own canvas by taking apart a ready-made painting canvas and pinning fabric across it. Then used a needle to punch holes to add the different coloured wools. I tried to play with texture by having some flat loops and some rounder longer loops.
The colours were inspired by the Ukraine flag due to the news from there currently as I see flowers as a symbol for hope.
I can definitely see myself using this technique again, but with more textures and it would be interesting to use materials other than wool, perhaps paint on the fabric first and then add different textures using this.
