Pattern for ear warmer: here.
Pattern for cherry blossoms: here.
For the branch, I couldn't find a patterns, I made it just from looking at the pattern's photo. I started off with a long chain, then double crocheted, half-double crocheted, single crocheted, and slip-stitched my way down the chain to make the branch start off thick and then narrow as it got longer. I added a new chain to the side of the branch where I wanted it to separate a third time. (For the first branch separation, I chained again after slip-stitching the main trunk of the branch, and the two chained ends could be arranged separately.)
I sewed it all on by hand with the twine-like yarn for the blossoms, and with sewing machine thread for the branch and pearls in the centre of the blossoms.
I fully recommend this ear warmer headband pattern. (I made a chain loop and sewed on buttons for attaching, with two buttons so it's adjustable.)
This item will be available at the craft show, as well.
Note: it's a little more green-y in person.
