How many bases overlap in recombinant PCR?

I failed to do PCR-based recombination when the overlapping was less than
12 bp. When I made new oligoes and increased the overlapping to 18 bp, it 
worked fine. 

No idea to save such little amount of money: if you have to optimize the PCR
recombination with shorter oligoes, it will cost much more than just 
make a long one from the beginning. They also save your frustration!
