I had never used boning before this project and was surprised how easy it was to use. It was lightweight fabric covered plastic boning and cut easily with scissors. You cut a length, slip the plastic out, sew the fabric channel down and then slide the boning back in. I cut the plastic ends in a curve so there would be no sharp edges. The boning is curved from being in a roll and for this collar, that was perfect!
My nails do not need cleaning, I poked myself with the needle under my nail and that is dried blood! At least I didn't bleed over the white lace! The creamy colored fabric on the bottom of the collar has velcro on the back and that is how it attaches to the bodice - remember the velcro squares?
In case you are interested this is the pattern we used and we made the view with the white dress with the collar.
