To execute this pattern you need to know (or be ready to learn :-) ) the following techniques:
-chain
-single crochet
-double crochet
-slip stitch (joining ends)
-picot (chain+slip stitch)

The pattern includes a scheme with a little list of symbols, and the full instruction written out.

You will need a small amount of cotton lace yarn (any kind) and a 1.3 mm crochet hook, a small piece of rubber band (circa 10 cm).

The sizing is very easy, you can start with any number of stitches that is dividable with 4. First you make a loooong chain, the lenght of which is up to you. I recommend measuring the recipient head circumference, substracting 10% of it, then from the number you got substract the length of the rubber band to get the length of the chain. So, as you see, it can be made in any size.

Since you will be adapting the pattern to the size needed, gauge is irrelevant.

Enjoy making and gifting/wearing it, and please visit my Ravelry store for more free patterns.
