Re: Help building an hour glass in BYOB
You're repeat(3) block seems along the right lines - though you're doing the same thing twice within that block which is a bit odd.
Beyond that, you seem to be doing something a bit odd afterwards, including jumping to a random place then turning 124 degrees once (rather than 120) which will be why things don't line up. When you've finished the first triangle, just go forward another 100 steps without turning, then draw the rest of the remaining triangle similar to before.
