Here is the finished Infinity Scarf made following this tutorial. Just in time to pop into an Express Post envelope to arrive interstate tomorrow (nothing like a bit of pressure to push me along).
I under-ordered fabric (only 0.5 yard of each) so I had to reduce the length of this scarf cutting from selvedge to selvedge. I also wanted to make this scarf narrower as my MIL is a petite lady and I didn't want the scarf to swamp her frame. The pieces I cut were 8" x 52" (the flannel was not as wide as the voile so I had to cut that as two 26" pieces and piece them together). Next time I would like to make the scarf longer so that it sits a bit lower. I already have a custom order from my Mum who was staying over last night!
EDITED: I forgot to mention that I didn't twist the scarf per the instructions in the tutorial because I didn't want the flannel to be a feature.
