crochet

My mum taught me how to crochet and I sort of made up my own pattern it is like this:
Pattern
4 chain,
thread over, go through by the knot, thread over, pull through, thread over, pull two bits of thread through, thread over, pull through, repeat 2 more times but put the hook in the middle of the ring you have made,
1 chain,
put the crochet hook in the same place and each time and do the same thing 3 more times,
1 chain,
that is the pattern, just repeat over and over until it is how you want it!!!

                          I have forgotten how many times I did it but this may be what it looks like.
                                                      This is how my one turned out!!!

my mum wanted me to write the right vocabulary so I did a key.
