All you need is a crochet needle of any size and some yarn
Remember to start with a slip knot
Remember to do one chain stitch before every row
Now it gets a little more complicated.
Crochet one double int the first stitch, then two in the next, for the third do just one, for the fourth and fifth crochet two and in the sixth just one again
Check and make sure you have nine in your row now
In this first and final step you will finally see.
Crochet on single stitch first then skip the next stitch and crochet five double stitches into the third one. Skip the next stitch and crochet a slip stitch into the fifth. Skip the sixth and crochet another five double stitches into the seventh finally crochet one last singe into the ninth and I'm sure you know how to tie things off?
Congratulation, you've crocheted a heart!!!
