My first model in Blender, made as instructed with duplicated cubes and three different materials (including the grass plane).
Just drag an image from your render output folder, into the message edit area.
So we can enjoy your work.
Welcome to this site.
Unfortunately we can not see your work, a few teething problems knowing how to post images here. Fed Pete explained how. An alternative way is to click the image icon in the middle of the row of icons at the top of the text entry box. Then choose your image by browsing your computer and selecting the image. then clicking the upload button that appears.
Put some arrows, knives, axes on to the board?
Worth the wait!
Good much overlooked bit of medieval military equipment.
Good simple model.
