Question for all you crochet experts here--
If I want to make a giant in the round blanket without a pattern do I just keep enlarging the same as the first few rounds? Like if I get to row 22 do I crochet two in the first crochet and then one crochet in the next 21?

I don't crochet, but it can't be too dissimilar to knitting... And it's basically maths too (physics student ahoy!)
I think your method will work!
Your circumference (distance around the circle,) is proportional to pi and the radius (distance in to the middle): so every time the radius doubles, your circumference should double also.
In knitting, the easiest way to achieve this is to double the number of stitches every time your row count doubles. So, row 2 had double the number of stitches of row 1... Row 4 has double the number of stitches of row 2... Row 8 had double the number of stitches of row 4...
(( you don't need to actually do all the increases in the doubling row (row 2, 4, 8, 16, 32) - you just need to have increased that much between doubling rows))
So... Talking specifically about your question: your method has you doing 22 stitches on row 22, then increases one per row to 44 stitches on row 44 (44 being the double of 22) which means both your stitch count.and your row number have doubled
If you want to double check, look up some free circular patterns on ravellery and see how they worked the increases
