We’ve got July weather in May, so am going to throw in something even more topsy/turvy: snowballs. Snowballs are like circles but without the curves. We will get to curves, but let’s start easy.
Please do two sides of snowballs in a size commiserate to what has already been done. No hard and fast rules about this, yet kindly chose the sides that will make the top more square than rectangular.
