First Impressions Molds' Annual Oops Sale!

I am completely new to molding and I went over to look at all the great molds. I feel silly asking this, but all of the molds seem like a positive instead of a cavity I could fill. Are they designed to press down onto the top of a material and make an impression? I did read about judging dimensions on the web site, but am not sure how to tell if a mold has more than one cavity. Any tips you could give me would be great, because I would like try these out, and an Oops Sale is perfect for me.

I'm not following your question - sorry. I generally press dough/fondant into the molds though (and then pop it out), especially when the molds are deep, as I feel I get better impressions that way.

Just completed a little shopping!  Can't wait to try out some fondant embellishments on my cookies!

I suppose the picture doesn't show the actual mold, but the fondant that comes out of it. A picture of the mold wouldn't show the details of the result very clearly.

But I have to admit, I don't get the part about more than one cavity either

Some of the molds come with more than one cavity - like their rose mold . . . there are several roses in the same slab of silicone. That's all that means, I think. And, yes, their images are of the molded end result, presumably because they show the patterns better than the mold itself. 

But some show the mold too, like this nine cavity frog mold: http://www.firstimpressionsmol...frogset12x114-1.aspx

Thanks for the clarification everyone. I wondered if I was vewing the final product created by the mold to show the design better, but they appeared to be made of silicone as some actual molds are, hence the confusion. Their site said they average the size of the biggest and smallest cavity in each mold to come up with the posted dimension, Also, to be sure and check the number of cavities when purchasing because there might be multiple cavites of an identical shape. (Such as 4 cavities that all produce an identical rose, so you can make several at once.)

None of the molds I looked at had more than one turned-out impression of the same shape, so I wondered how you can tell? I wondered if there was a general rule of thumb when shopping for molds online in general that I missed, and people in the know would be able to pass on. I should have just contacted them directly, sorry if I caused any confusion. (Important note to self - don't clog up the forum with questions I can find an answer to somewhere else!)

No need to apologize; the forums are here for asking just this sort of question.
