Patch for a rip in the lining of a down jacket An Eddie Bauer down jacket has a rip in the lining which according to the label is polyester.  It's a very thin fabric and it looked reminiscent of nylon but the label is quite clear that the lining is polyester.

Right now I am holding the down inside with a couple of pieces of scotch tape but would like to apply a less temporary patch.  Ideas:


iron on patch?  Maybe an iron even on low would be a bad idea?
duct tape?
paper tape?
some special sealant?
hand-sewn patch?  I am good at sewing on patches but feel unsure about putting even a fine needle into this very fine fabric.


We're not there right now, but some day this jacket will need washing.  So ideally the patch would hold up in the wash.  (The label says it is washable with TLC - tender loving care.)



Edit: If the following is successful I'll post it as an answer.  I read that


  Misty Fuse is [a] fusible web product that adheres two layers of fabric together. Misty Fuse performs the same function as other fusible web products but is very sheer, light weight and does not add stiffness or bulk to the layers of fabric joined. Misty Fuse does not have a paper backing. Misty Fuse can be used with very sheer fabrics and lower temperatures.


That's what I plan to use.  (I found out about a product called "Tenacious Tape" which according to some Amazon question answerers can't be relied upon to stay put during washing.)



Another update.  I started to feel uncertain about using an iron at all, even on a low setting, so I called Joann Fabrics (which sells a lot of notions) and they recommended Liquid Stitch - extra strength that allows for dry cleaning.  (The regular version allows for washing but not dry cleaning).  So that's my new plan.  Along with a very lightweight black patch with pinked edges, tucked inside the rip.  They said I'll have time after applying the adhesive to position the patch just right before applying pressure for the bonding.
When i worked at a tailor shop, we had single side fusible backing to repair the liners of the tuxedos. It came in black or white, was placed on the inside of the tear, ironed into place and then, if it was a large tear, hand stitched.
    The easiest thing to do in this situation if you don't need to stock up on this type of product, is to take the jacket to a dry cleaner or tailor shop and get a quote on the repair.


If you want to buy the interfacing, look into Pellon Shape-Flex Interfacing. Instructions are below the image.


Quickly looking online, the example above is the closest thing I can find to what I remember using without actually touching it. It was malleable and had a knit texture to it, this example says woven, so the texture may be different. You'll want to find something that matches your repair fabric. The fabric shop may sell facing by the foot or yard. (editorial - You really do not need an entire bolt unless you're going into the repair business. A little goes a very long way.) 

Instructions: You only need to cut as much as you need to hide the tear. The facing goes inside the tear, adhesive side touching the lining. Then iron with a press cloth to protect the polyester. As stated above, if it is a large area, it's good to hand stitch the tear for extra security. 

For a hole, place the facing inside the hole, adhesive side against the lining, then place a small piece of matching fabric over the facing, use a press cloth when ironing. Then hand stitch if necessary.
