Bender Board - questions

Have you used bender board to create winding area's in your yard for containing garderns? How do you attach it to the ground? Is there a product that would work better? I need to 'reduce' my mowing area & create a new large dry shade garden area on the south side of my house (yes south - its shaded by the nieghbors house & our 2 large tree's). I thought about creating walls with flat rock stacking but I'm not sure about that either, I need 'cheap' ideas --- my hubby is on disability which make's the moola not stretch very far.
Thanks in advance for the advice !
