Another New Comforter Cover!

I recently made another comforter cover, for a different bed.   I used spare sheets to make it.  

For some reason, it makes me a little nervous to make things like this.  I end up measuring once, twice, three times or more, saying a prayer, crossing my heart, and anything else that I think might possibly help me avoid making a big error!  I guess I'm reluctant to cut into extra large pieces of fabric like this.

I wanted the cover to sort of echo the painting in the room, so I made the balance of the stripes lean toward the darker blue on the left side and toward the lighter blue on the right side.  I'm happy with the result.

The pillowcases included in the sets are king size, and our pillows are regular size.  So I plan to "shorten" the large cases down to normal size, and use the leftover pieces of fabric to sew a contrasting strip to the new pillow cases.
