When you yarn over and pull the yarn through your stitch, bring it taut (but not cinched down) on your hook, then twist the hook so that the hooky part is facing into the corner of the stitch (it should be clearly visible) and you can pull it through easily. This is how you make your nominal stitch size. By doing it this way, you should be reasonably sure that all your stitches are the same size and that they are the correct size for whatever hook you are using.

I made a set of romeo and juliet dolls in ninth grade for an english project. I made a [terrible] poncho in 11th grade when I was into such things. I made a free-form "razorpig" doorstop for my mom for christmas one year (I dont' recommend stuffing these things with shredded paper!) I made stu a scarf made out of granny squares (like... idk 10 or 12 of them, each about 8" wide). Haven't done anything lately. Lola likes to unravel my yarn.

I can do some videos if you'd like, Rye. I remember how frustrating it was when my grandmother taught me xD
