I have 2 welsh slate planters - easy to make even without the wooden box inside. Find 4 slates that will form a box shape ( 2 of one size, 2 of another). Just drill holes in the corners of all the slates and thread wire through, and twist tight. Water drains out through sides so no need to drill holes in the base. Good for echeverias and cowslips. Will put a photo up on 'Sue T' very soon.
