Not making palm trees given the fact you can't bend bricks; Crepe, you have 2 links that send me to the google images page with tons of images
please be reasonable here guys, I need bricks that would look good in blockland that would serve as a good looking brick in many cases, sort of similar to how the default bricks look
the 4x4 round dish and the sloped brick curve top brick are the only ones I feel like I'd actually enjoy creating/would fit in with blockland relatively okay
