My 12 year old daughter has a bit of a flair for art. She has expressed a desire to explore this flair for art, on her bedroom walls (typical teenager!). Whilst I would like to support and encourage her talent, I am a bit reluctant to let her do it on her bedroom walls, just yet. I had suggested as an alternative, that she might like to buy a blank canvas, for example, and take some time to plan and draw, then paint what she wants to on this, and then see where we go from there. The problem is that I have no idea about drawing/painting on canvas or expensive this type of project may actually turn out to be, and was wondering if anyone could advise?
