Three-dimensional thinking

Recently, a designer specified the following for a bay window in a dining room: Make four tightly folded blinds in a semi-transparent fabric, interline them and line them with blackout lining. The blackout spec was a mystery in itself: why in a dining room? (See also below, ‘Fabric choices for Roman Blinds‘) If these blinds are pulled up, the many pleats will cause a great deal of bulk which may be acceptable in a straight window, but for windows with an inward angle, Year 8 maths might have told them that bulky blind folds on inwardly angled windows will get in the way of each other. In the end, I re-designed them all so they look smart and fit well. If you have a bay, go for a curtain.
