We have now created a space (TR8TOG) for an additional Bavarian circle (8 TR) to go into in the next even-numbered round (as seen in picture 5 above). With every odd-numbered round we work, an additional space will be created, which will then be occupied by a Bavarian circle on the following round, thus creating an increase every other round. Keep going in this way and create a Bavarian square of your desired size!
Round 4 (color B): *CH 2, 12 TR in the top of next TR4TOG, CH 2, SL ST in the next SL ST. CH 2, 8 TR in the top of the next TR8TOG, CH 2, SL ST in the next SL ST. Repeat from * 2 more times. CH 2, 12 TR in the top of next TR4TOG, CH 2, SL ST in the next SL ST. CH 2, 8 TR in the top of the next TR8TOG, CH 2. Join with a SL ST in the beginning SL ST.
