|I now highly recommend this alternative to traditional metal boning or plastic boning: 3/8" heavy duty ties and liquid electric tape for smoothing the tips. Yes, seriously. These plastic ties are surprisingly similar in feel to whale boning of days gone yore. Seriously weird but true. They work beautifully and have the perfect stiffness and flexibility. I bought mine at Home Depot in the 24" lengths but they come in 36" lengths also. A package of 10 are $5. (They can be ordered in colors; I just bought the off-the-rack white since they would be encased in a cotille foundation and not show.) One really nice thing about using this for boning is that no extra tools are required -no fancy cutters, rounders, or tips. You can cut it with kitchen shears or heavy craft scissors quite easily, round it with the scissors, file it with any jewelry file or fine grit sandpaper, and then dip it in liquid electric tape (also from Home Depot) or even acrylic paint if you want to finish off the edges so they don't rub through your ribbon channels. I do recommend dipping the already rounded ends that come on the ties. I used their rounded ends for one end then cut the other end for the proper lengths I needed. Their ends are more rounded than I attempted to get mine which is fine, but they are slightly rough enough that I strongly recommend still dipping them if you use them. The liquid tape dries very quickly by the way. This is highly unconventional and probably turned off a few of you, but it's amazing. Please do consider it. And just because it's plastic, keep in mind it's nothing at all like the plastic boning you can buy at JoAnn. Not even close.
