First grafting attempt: 3 of 20 took — larva age, dry vs wet, or a weak cell builder?
Third-year keeper in Uppsala and I finally tried grafting on Wednesday. Results are in: 3 accepted cells out of 20 grafts. I'm weirdly proud of the 3 but obviously want to know what sank the other 17.
My setup: Chinese grafting tool, larvae from my calmest colony, into a queenless cell builder I made up that morning from one strong colony (shook maybe 3 frames of nurse bees in, plus a frame of pollen and open honey). Grafted dry. I *think* my larvae were the right size but honestly some were probably too big — the difference between 12 hours and 2 days is harder to see through a veil than the books admit.
Where do experienced queen rearers think the points went missing — larva age, dry grafting vs priming with royal jelly, or a builder that was only queenless for a few hours?

Three on the board first try is a pass, not a fail. But your biggest leak is the cell builder, not your hands: made up the same morning means the bees hadn't yet FELT queenless — acceptance jumps massively when the builder has been hopelessly queenless for 12-24 hours before grafts go in, packed so tight with young bees it looks overcrowded, and fed thin syrup for 2 days beforehand. Second leak: larva age. Target under 24 hours — the larva should be barely bigger than the egg next to it, a tiny 'c' in a shine of jelly. If you can see it easily, it's usually too old. Fix those two and dry vs wet becomes a rounding error.

Agree with AlpineCarnica on priorities. On the dry/wet question since you asked: priming cups with diluted royal jelly can bump acceptance a few percent and stops larvae drying on a hot day, but plenty of commercial rearers graft dry forever. What matters more is speed and humidity — cover your graft frame with a damp cloth, work fast, and the larva rides over on enough of its own jelly. One trick for aging: cage the queen on an empty drawn frame for 24 h, release, graft on day 4. Then every larva is the right age by construction.

The damp towel and the confined-queen frame are how I finally got consistent. Also check your eyesight setup honestly — a cheap headlamp and reading glasses doubled my acceptance in my forties. Nobody puts that in the books either.

This is gold, tack! Round two planned: queen confined on Sunday, builder made queenless Wednesday evening and fed, grafting Thursday with a damp towel and, yes, the headlamp. If I don't beat 3/20 I'll be back with more questions.
