Why spend tons of money on embelished cardigans when you can do it yourself!!
Unfornately I did not take pictures of the process, however I'm sure you all can do with out the pictures.
Using yarn from your stash crochet any flower, bird, or figure that you wish. I used the flower and bird brooch pattern from Crochet Adorned. However, I am sure you can find free patterns on the web.
Pin the bird and flower (or whatever you crochet) on your cardigan. Make sure to try on the cardigan with the crochet adornment. It may look different when you try it on. Be careful not to prick yourself with the pins.
Once you are happy with the placement of the adornments, sew them into place by using a sewing needle.
Then, if you wish, sew on beads. Remember to use a sewing needle is smaller than the bead hole.
