Thanks for all the replies. I already had the calculator downloaded and
forgot about it
The core is wound.

When I enter T68-7 and 60 turns, the mini Ring Core Calculator show
18.7uH. It also says the max wire size is 25 gage. So, 26ga would be
tight, anything smaller would be good unless too much current will be used.

The wire size of a toroid affects its inductance and Q. Those effects
are small and the values in most circuits aren't sufficiently critical
for them to matter. The toroid cores are not precision components, and
wire winding technique also changes inductance. Stepping up or down a
size or two from the recommended one will usually work just fine so
long as the turns fit.
Wire size also affects current handling capacity. It's not likely to
matter in any QRP design, but don't use tiny wire if you build a QRO
radio or tuner!

As long as you can get the number of turns on the toroid you should be
good to go.

I'm I have some enameled wire that is smaller than #26 .... I am
guessing
probably #28 or 30.
My question is: can I use the wire I already have or do I have to
obtain
the specific wire called for in the parts list?
Can

How critical is the wire size when winding a toroid?.
Specifically... I have to wind a T68-7 core with 60 turns of #28
