A question on planting seeds

I'm just wondering if anyone knows whether it matters too much if I happen to put too much of a layer of soil over the seeds when the packet specifically says that there should be a "very fine sprinkling"? I have put about half a centimeter of soil over the seeds. Will the seeds still come through?
Also, the packet says that I should put the container into a sealed polythene bag, but I have put them into a propagator instead. Does this matter too much?
Many thanks,
Joseph

Normally, the seeds are covered with soil to a depth of 1 and a half times the diameter of the seed.

1/2 cm shouldn't matter.
propagator? If you are talking about a nursery flat w/ a propagation/ humidity dome or plastic wrap, you should be fine with that also. Just watch to ensure it does not get too humid nor too dry and every once in a while circulate fresh air. I use a light dusting of cinnamon on my flats. It has been reported to have anti fungal properties as has tumeric and chamomile tea. The cinnamon seems to help me but I also use Neem and fans quite a bit in my GH.

It's going to be tougher, as I'm guessing these seeds are small and so the seedlings will be small. It's a race to get tall enough to reach the light before running out of stored nutrients in the seed.
If the soil is loose, it will probably be ok.

They're trying to prevent the seeds from drying out during germination. If your propagator has a high relative humidity (better yet, a mist system!) it's even better. Seedlings in plastic bags have a tendency to damp off. Having high relative humidity and good air circulation leads to healthier seedlings.
I typically grow seedlings under an intermittent mist in an area with good air circulation -- sometimes I help the air circulation out with a fan.
Plain sand as seed cover (or sand and milled sphagnum mix) is also useful in improving germination.
