Please bear with me. I am working my way through an illustrator course. One of the "assignments" is to draw something with the paint brush tool, then change the stroke from the basic stroke to chalk (or calligraphy, etc). So I draw my shape, click on it with the black arrow, go to my stroke box and click on "chalk". Nothing happens. You can see the thumbnail version of my document change from basic lines to chalk lines on the Layers panel. But not on the actual document. I am so confused. If I click on a brush stroke style before I draw. Then actually draw it, it shows up as that style (chalk for instance) but then as soon as I'm done drawing it switches back to the basic thin stroke line. Although the thumbnail version in layers is showing it as a chalk stroke. I'm probably doing something extremely stupid. So I am very sorry for my newbishness. Any ideas?
