The one thing that you might want to think about is that if you are using a vintage quilt, it might not be that sturdy. I could stand up to occasional usage but probably wouldn't do well with constant wearing and washing.

I had no idea young guys were wearing pieced and quilted jackets. How amazing! I'll have to google that.

Lots of great tips here! I also had no idea young men were wearing re-made jackets from quilts. I will try to check that out too. I am wondering if baby boys would look cute in them. I have a friend that just became a grandma. Thanks for all the help girls, I will keep my notes with the pattern for when I need to read them again.

OMG! A baby boy in a quilty jacket would be adorable!

I am in the process of piecing to make a quilted jacket using a "vintage" 90's jacket pattern. I plan to use only a lightweight flannel (no batting) to quilt the pieced fabric to, and not dense quilting, just enough to hold it together, hopefully the sleeves won't turn out stiff and it will be comfortable to wear.

I just saw an article with quilted jackets as "the thing" to wear this year. I can't believe it! Here is the link. 20 Quilted Patchwork Jackets That Are So Chic | Who What Wear
Now rev up those machines' girls. Time to use up those UFO's.
I just plan on making my original jacket idea right now but, who knows?

Thanks for that link, Red Garnett! Those are amazing. I'm just finishing up one that I started months ago. I'll post pics once it's done.

I made a quilted jacket five years ago which I still wear. It was the Tamarack jacket from Grainline Studios, my review is here.

I agree with others' recommendations about making the sleeve batting as thin as possible, they bulk up quickly and the armhole seam becomes a nightmare.

Also I would make the lining layer of the sleeves in a slippery fabric. I struggle to get my arms into the sleeves while wearing shirts made of anything but satin (LOL).

Have fun! I enjoyed making it.

A bit of a trip down memory lane ... back in the 90s the LQS had a class for making quilted jackets.

However, what we did was make the fabric aka the quilt, then cut the pattern pieces from it.
It was recommended to use a polyester cotton fabric for the backing/lining so that it gave some slippery-ness when putting your arms into the jacket. Likewise they recommended that for all quilts, particular big queen/king ones, to make it easier when making the bed. Some did and some didn't ... one used a regular poly lining fabric. Turned out it was a brute to work with when machine quilting as it was way too slippery.

If I was making it again ... and depending on your construction method. For sure I would use a poly lining for the sleeves. I think of coats/jackets where the sleeve innards are just too tricky when putting your arms in. Might be a mid-way compromise to the problem that @dunster has with her jacket.

Already mentioned by some others ... flannelette for batting helps keep down the bulkyness and stiffness. Also, important to quilt lightly, as the more quilting, the stiffer the end result.

@RedGarnet222 ... Will look forward to your creation!

Yes, yes, yes! Please post your creation for us to see!
