Wheel re spoking

Hullo, so ive recently refurbished/rebuilt an old single speed frame.ive stripped out the old spokes and repainted the hubs. I wanted to know about what would be the best way to have the spokes in the wheel. Ive seen amazing looking wheels with maybe 20 spokes and it looks very clean. Just wondering if because of the rim i have it has to be done in a specific way. My hubs have 12 holes either side. 24 per rim. I've seen online tools to work things out but i dont know the make of the rims or hubs.

do radial front and 2x rear. do not use your old spokes though. you will need to use a spoke calculator to find out what length you need. you can input your hub dimensions and rim erd to find the length you need. the spoke calcs are pretty straight forward.
a 24h rear wheel laced 2x will put the spokes at the same angle as a 32h wheel laced 3x so it will be just about as strong in terms of build strength, minus the fact that is has 8 less spokes to share the load.

If you are reusing old hubs, I would obey the lacing pattern that was previously used.

Just for my curiosity, what is the reasoning behind this?

On aluminium hubs, the spokes press grooves in the flanges. These grooves act as stress risers.
While failure isn't certain, adding more stress risers is a principally bad idea.

Bikes: too many bikes from 1967 10s (5x2)Frejus to a Sumitomo Ti/Chorus aluminum 10s (10x2), plus one non-susp mtn bike I use as my commuter

We also have to consider the original question, which implies that the OP is in unfamiliar territory.

Following the logic of learning to crawl before he goes out for the track team, simpler is better.

So, I suggest he rebuild them as they were, even using the original spokes. If he's unsure of the number of crosses, he can input hub and rim data into a spoke calculator and see how many crosses his spokes are right for.

Yep. I've seen pictures of hub flanges that cracked and broke due to being laced differently from their original set. But like you said, there's a decent chance you can get away with it.
