The other day, I came across this link from Red Heart. It took me to a pattern for crocheted maple leaves that they strung into a garland. I bookmarked it and then shared it. I decided to try it out using scraps from the blanket I made.
These are quick and easy to make and I like the way the leaf came out! It's just three rounds and a couple of ends to weave in.I have not tried this, but it looks like you could make a few of these in a thinner yarn (I used worsted weight and an H hook) and join as you go in a circle to make a doily. Should work to join at the ends of the stems and at each 'petal' on either side of the stem.
Happy autumn crocheting!
