Baby blanket in baby sport weight yarn with size G hook. I work rounds until it measures 33 1/2 inches across. I have made several as gifts for nieces and nephews for first babies. I will need 10 more, so I'm still making these blankets.
Afghan using worsted weight yarn and size J hook. I used left over yarn from other projects until I thought it was big enough.
Patterns suggest yarn weight and hook size and often say to make a practice swatch of so many stitches and rows to check your gauge, and to change hook size until your practice swatch measures so many inches. This is important for clothes to get the right size, but not so important for blankets, afghans, or doilies.

Work in rounds, alternating rounds of large shells and small shells. Increasing every other round (large shells) helps the afghan lay flat. Work as many rounds as needed for desired size.
