Simple geometric designs for cross-stitch

Hi!

I’m making a metric ton of bookmarks, little framed signs and stuff for Christmas (and post-Christmas) gifts. There’s something I’m having major trouble with, though, and that I for some reason can’t find good examples of online. It feels kind of silly: Simple geometric designs, most of all circles and five-pointed stars in smaller sizes (about 20 x 20 squares). I’ve tried for days to create them myself on (squared) paper, but can’t seem to get the shape right. It’s maddening! And not my forte.

If any of you know of any cross-stitch patterns for smallish geometric designs, or have a tip for how to translate them onto a grid, I’d be very grateful.

(Circles and pentagrams, you ask? Why, it’s a heavy metal cross-stitch bookmark of course.)
