I agree, traditional media gets you out to the masses, but the cost is pretty high and the sales orders that you receive may be more than you can take. I'm pretty new to leather craft as a hobby btw, so I might be wrong.. My experience is that online media especially for the handicraft can help small businesses (or workshops) grow slowly, because the amount of exposure you have at that point in time usually translates to the amount sales you can handle. But of course, it still takes a considerable amount of time to accumulate enough content to make your first few sales.
On a side note, (I am very new here), is there any marketplace that specializes in trading leather crafts and/or leather related goods?
Thanks!
