Im thinking of getting a cintiq or a simmilar off brand product, but what else are great things to buy if you can afford it?
if you can afford it, stretch your own canvases. the difference between the pre-stretched canvases and cotton duck or linen you stretch yourself is night and day. it's also great because you can take canvas off stretcher bars and reuse them for a new painting, so down the road you are saving some money. it's just an investment up front to buy the stuff you need.
Yup, even better us to get a high quality drop-cloth and use it instead of art store bullshit. Often very similar thread count and way heavier.
Also, hardboard and gesso it yourself is a great "go fuck yourself" to op'd art stores.
If I had to prioritise, Ill start with a new spacious apartment/studio, then a drafting table and a setup that doesnt break my back. Thats all I need right now; I could do with my current supplies, I just want to be more comfortable when Im working.
A cintiq and a second monitor would be next, to make my workflow a bit more efficient (possibly more accurate hand/eye coordination on cintiq, and so that I dont have to alt-tab for references)
