The interweave stitch is very beautiful and a lot easier to do than it looks. It just contains basic stitches like chain stitch, slip stitch and double crochet stitch.
This video is one of my favorite tutorials although it is in Spanish. Even though it is in Spanish, it is still fairly simple to follow along. To make it easier, the beginning is as follows:
Slip knot, chain 40, slip stitch into the first chain(beginning) to create a circle. Make sure to keep your stitches untwisted. Then chain up 3 and double crochet into first stitch over. Continue and follow along the tutorial.
