The loops should be firm but not tight. When all the chains have been used up there should be a group of loops on the mandrill divisible by four, five or six depending upon your plan. Make four, five or six single crochets into the loop. Slip off the next sequence of four, five or six loops, rotate counter clock wise and make four, five or six single crochets into the loop of threads. The slip stitch is made only into the first set of loops.
Single crochets are sufficient for the rest.
Place the loop from the last single crochet back on the mandrill, rotate 180 degrees so that the bulk of the work is on the left, the mandrill tilted to the left, and pick up a loop through each single crochet and place it on to the mandrill. Repeat from line 3 until the work is as long as needed, or you fall over dead. Finish as below. As you become familiar with this form of crochet it will become obvious how to increase and decrease stitches to make shawls, sweaters and such. When putting loops onto the mandrill have the work on the left side of the mandrill.
