In the past I have stretched my own canvas on to wooden frames. However, although cheaper than a ready stretched canvas, it is not one bit convenient. So currently I buy ready stretched canvas.
For canvas, I go to Evans on Capel Street.
My last expedition to Evans was on Saturday and I hired a GoCar van as the canvas I proposed buying would not fit in my Smart Car!!
Along with canvas, I buy oil sticks and brushes in Evans.
For other art supplies I visit Tiger and also sometimes hardware stores for domestic paint.
And finally I get my spray paint in All City Records where I have a browse at the vinyl when I visit which always makes for a fun trip that Enid likes to do with me.
