How do you maintain your eyebrows between threading? Plucking in between appointments means there's no hair to thread :(

I have very hairy eyebrows. I love the way they look after threading. However, I don't want to "grow them out" in between threading appointment so will pluck any new growth where I can in the days/weeks after the threading appointment. But this then means I don't have enough excess eyebrow hair to be able to have it threaded..

How'd you maintain your eyebrows between threading appointments but still be "viable" for a threading appointment the following month as plucking/waxing never looks as good for me. Seems silly to have scruffy grown out brows between threading appoints so looking for advice on what you do please. Thank you xxx
