I've never sewn with ticking before but every time I hear the word it makes me think of Little House on the Prairie and how they would empty the straw ticks during spring cleaning and fill them with fresh grass and straw. I always thought it was just a specifically striped kind of cotton, but it's not. It doesn't really feel like cotton, it's much slipperier and a little bit more ravelly. It might not even be cotton--I honestly have no idea.
I did some of my best sewing on this rectangle. To get the stripes to run vertically I had to sew a seam in the middle as the fabric wasn't wide enough. A French seam is a little too bulky (as I learned with my sister's cherry curtains) so I used a flat fell seam. You can't even tell it's there. It took a teensy little bit more work but it's so flat and smooth. I was silly excited because it was the first one I had ever done. Stripes make things quite easy to line up just right. The hems all cooperated and didn't squiggle out of place or anything--they stayed put just where I said to. It made for a quite relaxing evening of sewing.
My sissie's co-worker was quite pleased with them and said she'd remember me for future tasks. She wrote me a nice little note, thanking me for making her exactly what she wanted. She even sent pictures of it all hung up (it's always fun to see something you've made out in the world somewhere).
