This is a super simple pattern for a spool pin doily. If you have basic crochet skills you probably don't need these step by step instructions, but for those who have never crocheted in the round it might be helpful.
If you've never crocheted in the round, remember that you have to join each round to the top of the first stitch of that round and that first stitch will actually be a chain that is equal to the first stitch in the round.
For example: If the first stitch in the round is a dc (as in this pattern) the first "stitch" is a chain 3 which counts as a dc stitch. When you join that round, you'll join with a sl st in the third chain stitch.
After joining, you'll need to sl st into the starting place for your next round as in Round Two below where you sl st into the ch 2 space of the round below.
START WITH A LOOP
ROUND ONE
ROUND TWO
ROUND THREE
FINISH OFF
This can certainly be made fancier, but this gives a good basic starting pattern that is just the right size for a spool pin doily.
Just for kicks, I drew a chart of the pattern. For more complicated work, I follow charts like this
