How do you fix a cracked seam in a down jacket?
First shake the down out of the hole, then sew with small, tight stitches in strong polyester thread. Start a little before the crack and finish a little after.
Which thread is best to use?
Polyester thread is best because it is durable and does not break as easily as cotton thread.
Can you use patches on a down jacket?
Yes, self-adhesive repair patches work great and reinforce the fabric. They can be applied to both the inside and outside.
When should you send your jacket in for repairs?
If an entire channel has burst, if the down has already leaked a lot, or if the fabric is too thick to sew by hand, then it is best to take it to a tailor or workshop.
