I mostly use a combination of tape and ty-wraps.
It should be noted that 15 turns on a low-Q toroid (Fair-Rite #31, #
43) will produce a resonance in the low MHz range that won't be very
sensitive to precise positioning of the turns. 15 turns on a high-Q
toroid (Fair-rite #61, #67) will resonate above 15 MHz and WILL be a
somewhat sensitive to turn geometry.
