Garden Design Ideas

I want a small, fairly simple, garden wall built and am seeking a free software program which would help me sketch out some designs and help me estimate how many bricks are needed. Ideally i’d also print this out to show the builder. Any ideas?

I’m looking to buy Landscape Design software for DIY projects. I’m reading good things about Better Homes and Garden Home Design Suite and Punch! softwares. Anyone used them or have any recommendations for either, both, or something else?

since my bf is studying landscape design I thought of getting him this thing that you build a model on ( plz let me know what is it called, you know it’s a white thick thing ) anyways i was wondering how to make it, like I’m not gonna stick anything am just gonna prepare the materials for him so he can design his own yard 9 garden ) so i made little trees out of tooth sticks and cotton i painted them and they look like real trees lol anyways what else do I need? plz don’t forget to give me the name of that thing which is the base of the model garden
