I'm mostly showing my supplies because I know how expensive art supplies can be. What we use is such an investment. I've never felt comfortable spending so much on things like professional art markers of any brand or paying more for any name brand in general that made my wallet hurt.
At the same time, I've always believed that brand name never really mattered that much because it wasn't the price or brand that entirely made the piece, it's the style and technique. It was how you apply your skills that truly made the piece. Yeah, sometimes there's some stuff that can be improved upon or enhanced by using higher quality materials and not everything is cheap either. Which I guess can be great thing about mixd media. You can use an assortment of "cheaper" stuff.
As you can see, my supplies (not including my pencils and paints) were built upon with deals. I'd say that at least 70% of my markers and pens were the result of good timing and sales. Even my sketch pads were the cheaper store brand/bought with a 40% coupon.
I bring up much of this information because when in some past art classes, it was always the expensive supplies that were pushed by my instructors. It was the material quality how some of my instructors judged my work--for good or bad. It was also the expensive brands that I could never buy in full sets...only the single pens here and there and those wonderful gifts that I got for birthdays and holidays (crayola and suitcase art sets). As well as those wonderful materials gifted to me by my lovely high school art teachers. I've never had a full prisma pencil set before and that 10 pencil set was pretty great to have.)
I hope that others can see that no matter what level of skill or quality of supplies, you can do anything with anything especially if you can't always afford certain materials.
