Very simple, perfect for beginners and relatively fast project - that is a crochet summer poncho I named Lily. I used very thin yarn YarnArt Lily Melange. Lily Melange is  100% mercerized cotton, sold in 50-gram-skein with 225 meters (1.76 ounces/246 yards). Recommended hook is 1.75 - 2 mm but I used 8 mm to create very soft and loose effect.

Summer poncho is one long stripe in rectangle shape sewn together (check photo gallery under this article). You can wear the tip of the poncho in front or in back. And if you want, you can easily make a headscarf out of it.

For the correct size:
width of the stripe is the measurement from your clavicular to elbow, this is the width of the base for the first row;
length of the strip is the circumference measured from one shoulder to the other and back plus you need to add approximately 20-30 centimeters to this measurement, e.g. I have 90 cm and the poncho in this pattern is 115 cm in length;
with this clues you can substitute the yarn, just follow the measurements.

For washing:
I recommend hand washing of this poncho. If washed in the washing machine, please use small laundry bag.

Edge around the neck:
I used SC for the edge around the neck. If you crochet only one SC per a row, the edging will be very firm. For softer and more flexible edging use the crochet scheme 2 SC - 1 SC.
