I've done it just recently with the bunny slippers. I didn't like how the footing ended up looking so I added a few more stitches and the toe ended up being more rounded at the top and bottom instead of pointy. Which made it easier for the toe area to be rounded when seamed together. Thank God I wrote it down as I was doing it.
I now have to sit down and figure out how to write the pattern for adult feet since my mom wants a pair.
