Sewing Rusted Fabrics - The Fabric Rusted Through Now What???

My fabrics have rusted through now what?  Can I still use my fabrics? 
The anwser is yes you can still use your fabrics, with a little help from a quilters best friend iron on stablizer!

A small tid bit of rusted fabric that once lived in the fabric in the preceeding photo.

Heavily rusted areas that glisten, this glistening is due to the iron oxide deposits on the surface of the fibers.

A view of the area I will be working with, complete with a hole that has rusted completely through the surface.

Mistyfuse TM stabilizer, I pressed my top fabric first and then sandwiched the Mistyfuse TM between the top fabric and a piece of soft cotton fabric, as I will be using a wool batting and another backing fabric.  Needling is imporant for this piece hence the reason I chose to use the flannel. Cotton scrim is also suitable for this project.

The stabilizer and backing fabric are now adhered to the front fabric.

Here you can see the stabilzer and the backing fabric peaking through the hole of the rusted fabric, click on photo for larger detail shot.

Full view of the fabric after the backing fabric and stablilzer are put in place, I am now ready to make my quilt sandwich as usual and begin stitching.

Removing Excess Rust - Process One The Soak Method

Supplies for removing excess rust using the soak method: gloves, tongs, long spoon for stirring, bucket, warm water, baking soda, plastic to protect work area, rusted fabric. 

Remember all items used for this project are NOT to be used again for genearl cooking/eating purposes.  Please use studio dedicated tools ONLY for safety's sake!!!  Wear gloves and old work clothes if you do not wish to stain your hands or your clothes.

Add to your clean bucket 1 quart of hot water and then mix in 1/4 cup baking soda.

The water will become fizzy, this is ok.

View of  your baking soda water, this is what you will use to reduce the rust on the surface of the fabric

Push your fabric into the warm water solution and thoroughly wet out the fabric making sure the fabric is beneath the waters surface, add more warm water if needed.

This is what your fabric will look like in the bucket, after about 3-5 minutes your water will start to change color as the baking soda knocks the rust/iron oxide particles loose from the fabrics surface.  I genearlly allow my fabric to soak overnight, if the rusted area is excessively heavy I will change the baking soda solution. You can save this solution as a mordant for dyeing other fabrics, you could pour it into an old soda bottle for later use.
