I am /did have trouble right from the start with making mountains . Some of it is probably ( most certainly ) my fault for not wanting to spend the money on "proper" materials . I was able to find a little casting plaster in a craft store 2 hours away so I picked that up to cast the rocks in the molds , But I just couldn't see fit to order 4-8 pound cans of hydrocal and pay the shipping , so I went with drywall mud . The mud and casting plaster , being different materials naturally took colors differently which doesn't look well . Attaching the molded pieces in a fashion that looked good and natural was a task well beyond my abilities too ! Then I tried some mountains out of all drywall mud thinking I would just carve the rock into it while still soft , I mean how hard could that be , right? Well it was easy to carve on it , but not easy to make it look like something real , or even impressionistic. My mountains look like a grade school child was playing in the clay ..... Then I thought , maybe painting a backdrop would be easier , I mean I have watched Bob Ross paint entire pictures in 5 minutes so how hard could that be ? I watched Chris Lyon's 5 part video several times and have to say THANK YOU CHRIS , not that my backdrop really turned out well but his instruction was invaluable to me for that type of painting . So then I figure I should try to make some trees and settle on Landel Browns method for furnace filter trees . They actually turned out acceptable , not near as nice as his but OK , so I cant complain a lot about the trees . They will probably be the best thing on my layout . Maybe I should just model a road DEEP ,DEEP in the forest.. Thanks for the tips guys . I will try to implement them as I can .
