and household items like?
Anything you can find around the house.
Even things you might find boring to draw.
Get into it and figure out the construction.
It's good to do the same object from multiple perspectives.
Here's some examples from my sketchbook from years ago i was able to dig up:












Couldn't find my other sketchbooks at the moment.
For the 1000 teapots you don't HAVE to use reference, altho it is recommended to start with.
There are different strategies to the teapots if finishing within the time limit is important to you.
You could draw 100 really shitty ones in 10 secs each.
Then take your time on the next 10 and make them nice.
Then do another 100 shitty!
Try realistic, stylized, themed, give them personalities, etc.
There are no rules besides the original guidelines.
Just go for it and see where it takes you.
Make it fun.
cubes from imagination?
Again you can use reference at first.
But then go crazy.
Try different types of perspective.
Make up ideas to keep yourself entertained and make the image entertaining.
how big do you think i should make the sprites?
I realize my examples are on paper, but the same exercises could be done in pixel (im considering doing the teapots just for fun myself, altho ill get no where near 1000!)
I'm going to do a row of 8x8, then a row of 16x16, then 32x32, 64x64, etc, and see how far that gets me.
But its up to you.
Be creative and fill in the blanks.
Also these aren't just random exercises I made up.
I've completed these in the past and found them to be useful.
Something that I should probably do more often.
If you're up to it, post your progress just for fun.
