I have tried searching the form for info on sources for solder paste but have not had much luck. "solder paste", solder AND paste; no joy.

Where do you find reasonably priced, fresh solder paste, quanity 1 ?

Unless you are doing work with no-lead packages or packages with bottom side heat sink slugs, it's best to practice techniques like drag soldering for fine pitch devices.

I work a bit with SOIC and 805 size, parts. The drag method works well for ICs but I am having a tough time with resistors and caps. I know this sounds backward.

I seen a video where they applied paste to the pads, positioned the resistor and heated it. It nearly jumped into alignment. No tweezers or hemostats!

I want to try the smaller parts. Much of the 'neat' stuff seems to be in increasingly smaller packages.

In time I want to try the Sparkfun fry-pan or a revamped toaster oven with the paste.

There is a hot tweezers for the MPJA soldering station. I splurged and added one or two or each tips, an extra handle/element, and the tweezers.
I have used the tweezers on SOICs but not resistors or caps.

Maybe I should build a few more boards with the equipment I have and see how that goes. I think that is what most everyone is getting at?

@John
I made a simple wire hold down jig similar to what you described. It helped.

A bit off topic:
The current plan is to build a few modules that the kids can plug into their breadboards to make building faster. Various people have talked about such things here from time to time.

One would be a processor board with ICSP connector, crystal setup, reset pullup, and maybe a few jumperable status leds. And sort the port pins so they come out in order. The kids will be using the Junbugs for a few weeks so I have some time to ramp the stuff up.

... and then poke down on it with tweezers to
shoot them up into an orbit.
