Stitch twenty-two of the TAST Challenge hosted by Sharon Boggon at Pin Tangle is the buttonhole wheel. As ever, Sharon has posted a great tutorial describing how to work the stitch with lots of inspirational photographs giving you plenty of ideas how to use it.
The buttonhole wheel is a stitch that I am familiar with and I have used it quite a number of times on my CQJP Challenge 2015 blocks. These have mainly been added as flowers but, as you can see from the top photograph, you do not have to stitch the whole 'wheel' as a section makes a nice decorative stitch too.
I think it looks particularly nice stitched in variegated thread and that is what I used to stitch the examples I added to my sampler.
It also gives a nice effect on the back of the fabric and, on past occasions, I have actually stitched it so that this fluffy flower appears on the right side of my stitching and the buttonhole wheel on the back!! (Of course, in those instances, I would hide the knots!)
You don't have to extend the buttonhole stitch all the way to the middle of the circle if you don't want to (as can be seen in the photograph immediately above). This gives the wheel a slightly different appearance and, when stacked as they are here, they make a great 'hollyhock' flower!
