Both patterns required that we calculate (or at least approximate) slopes; on the knitted torus, the six edges emanating from each vertex have three different slopes, and on the crocheted torus the six boundaries of each country have three different slopes. The slopes could not be calculated in any straightforward way because of the bridge stitches ✐ ✐ ✐ ✐ ✐ ✐ ✐ ✐ The Seven-Colored Torus 31 Figure 6.

They decided they would be content to be able to produce approximations to regular b-gons as long as they could depend on the error becoming smaller and smaller. This seems reasonable since Euclidean constructions are only perfect in the mind—after all, what is actually produced is a function of how sharp your pencil is, how steady you hold the compass, and how carefully you place the ruler. Thus, even with Euclidean constructions, there are inevitable inaccuracies, due to human error. As you will soon see, in the systematic folding procedures we use, every correct fold that 1 The paper-folding result came about by trying to construct hexa-flexagons, written about by Martin Gardner in January of 1957.
