Yeah for a cheaper one making a case yourself would be alright methinks. But if you spent a lot of money on it, definitely protect your investment. I got an iPad Pro and I don’t have a case yet which means I’m very nervous even carrying it around the house. I refuse to entertain the thought of taking it out of the house, too.
As for stands I mean.... if that’s how you draw, great, but you don’t need one to make better art yaknow? I draw with my iPad just sitting on my lap but.
