everything sounds "sketchier"

[in quotation marks, and with a little tweaking.]

compare this:

the art lesson will be after school on friday, at my house. you require newsprint paper. also you need charcoal pencils, sketching pencils, putty erasers, and normal erasers. the teacher will provide blending stumps. you can get your supplies at michaels.

with this:
the "art lesson" is friday at the usual place, usual time. you need "newsprint." also you need "charcoal" pencils, "sketching" pencils, and two different kinds of erasers. "teacher" will provide the blending stumps. contact michael if you need supplies.

[i actually have an art lesson on friday. i have all my "supplies." i mean, supplies.]
