Sewing Bowl A Cozy

I have been sewing bowl cozies for the last week! 

I was asked to sew some for the boutique where I sell sewn items.
I didn't know there were so many ways to sew a cozy. But a Google search came up with MANY!
I finally chose to use the method I saw in a video tutorial by The Crafty Gemini HERE.

I modified her shape and size, but the rest of the directions made it a fairly easy item to sew.

I cut my pressed fabrics and the 100% cotton batting using my 9.5 inch squaring ruler. Maybe if I had a 10 inch squaring ruler I would have used that.

I sewed a fabric square diagonally (wrong side on battinig) onto a square of batting using the "eyeball" method Vanessa described in her video. I found that if I gently held the point opposite the one feeding through the needle the stitching line was pretty straight. 

I did not cut the curved corners as she did, but if I had, it would have eliminated a tough job of sewing the pointy corners on my cozy in the final edge stitching.

I made a little cardboard marker for measuring the starting and stopping points of the darts.
I didn't mark a line, I just sewed from mark to mark, back stitching on the open edge(where my pen is).

I pinned the corners and the darts to match and sewed a 1/4 inch seam, leaving a starting and stopping gap for turning the cozy right side out.

Here is how I started and stopped my stitches. I came in 3 stitches from the edge, back stitched, and came back to the seam line, needle down and pivoted to sew the seam line. This helps make the seam fold into the cozy for easy edge stitching later.

I found That Purple Thang was the best tool to work the points of the corner out. 

Have you made bowl cozies? What pattern or method did you use?
