When I sprung for my first serger, I splurged and purchased a Baby Lock Evolve. It was a great decision and is a workhorse for garment sewing. I have to admit that I also like using the machine for less practical work as well. I love the versatility of chain stitching. I have used it for serger quilting and even this lacy baby bonnet. My daughter was too old by the time I braved this pattern, but I gifted the bonnet to a friend for her new granddaughter.
Don’t be afraid to try this pattern, “Evolve Serger Lace Bonnet” on Baby Lock’s website by Missy Billingsley. With a little planning, you will love using these techniques for other things as well.

The gist of the project is creating lace-like fabric by stabilizing tulle with wash away stabilizer and chain stitching the lace pattern. After that is done, your piece could be used in any traditional pattern!
HINT: Do make your tulle larger than the finished size by about an inch. The edges will be rough at entry and exit. You will want to trim these out of your final piece before assembly.
