Sewing flute case covers

Dear Fluters,

Home sewers might be interested in a method of creating flute case covers that is very easy, colourful and fun.

Flute case cover design in pdf.

I don't quilt myself, and made mine just from nice sturdy fabric, but a quilter on the flute groups was looking for a pattern to use, in order to create for gift case covers for students.
NOTE: Since every flute case is a slightly different size and girth, I think it best to make a test-pattern from scrap cloth first to get the dimensions right for ease of sliding the flute in and out, and to make sure that the triangle that buttons or velcros is placed correctly.
Best,
Jen
