How to stretch canvas case cover?

February 19, 2018, 4:54 PM · I took off the canvas case cover from my violin case a couple of weeks ago and now can't put it back on.
The cover is too tight/small.

It had been on the case for decades!

I thought of washing/wetting it.
I put it in the bathtub but I need something to stretch it out.

Any thoughts? This is a real heavy duty thick canvas cover.

February 19, 2018, 5:55 PM · Well, if throwing it in the bathtub (with water) to get it wet wasn't enough to get the canvas to stretch by hand, I doubt that spraying it from a spray bottle will help. :)

February 20, 2018, 4:20 PM · One way to stretch the case could be to fill it with heavy material, like bricks or sand, and suspend it for a while.

Note that wetting a canvas fabric will likely shrink it (think soaking new jeans to get a required tight fit).

There's a traditional method, which I was taught in my first job as a lab technician, of getting a very tight fitting lid onto a container - cool the container to shrink it slightly and heat the lid to expand it. Perhaps someone could think along those lines to devise a solution to the OP's problem.

Is this one of those $200 Jaeger covers? If not - maybe buy a new one.

My Jaeger cover has been off and gone for at least 10 years.

Here's a suggestion: generally the zippers on these covers break over time, and they are fairly narrow. Take the cover to a shoe repair place and ask them to put on a larger (hopefully metal) zipper. The extra size may give you the extra room you need. Soaking may work, but if it doesn't I can't see that anything else will.
When I was using my Jaeger case more, I chucked it anyway and used a cushy case cover. Much better protection. Those canvas covers are to modern cases what hobnail boots are to modern mountain climbing boots--obsolete.

February 23, 2018, 4:10 PM · Scott's suggestion is a good one, and it's roughly what I did with the cover for my double case - except that Eray doesn't repair shoes, but drycleans and repairs clothes. You may have to source the zip yourself on the internet - I didn't burden Eray with that job. I got my zip from UK Sewing Machines .
February 23, 2018, 4:46 PM · My one inquiry about zipper replacement would have exceeded the cost of the leather coat it was for. Scott's suggestion to replace with a Cushy cover appeals to me.
