For the ironing board holder, which will be on the same level as your other flange, we started with a length of 100mm pipe and screwed it into the flange. We then screwed an elbow onto it. Working across to the left, screw a 100mm pipe, a T, a 100mm pipe, a T, then a 100mm pipe then an elbow. When using the Ts for this section, make sure they are facing the opposite way to the flange and the final elbow is pointing up. Attach the brass end caps to the ironing board holder. When building the storage unit, remember to leave space for the shelf and plenty of room to hang your ironing board when putting your final design together.
