As part of our continuing quest to experiment with every possible fabrication technology, we recently came across an opportunity to try fabric printing services while outfitting our new office with curtains.

Roller blinds are a nice alternative to curtains with their simple appearance. However, most roller blinds are rather boring. You can have custom fabric printed at places like Spoonflower with whatever you want on them to replace the boring standard fabrics. (Perhaps the best use of custom printed fabric is the Tetris dress.) TrueUp has a great comparison of fabric printing services. If you prefer low tech fabric printing techniques, check out the round up at The Long Thread.

Roller blind hardware is available from other sources, but it’s hard to beat Ikea for easy and cheap. Their “Enje” blinds are inexpensive and quite hackable.
