The Upholstery Forum

I’m pretty green when it comes to upholstery, I am struggling to stretch the boxing correctly for a stool seat and it keeps wrinkling. Should I remove the boxing and take it in about 1/2” or add Dacron in the curved spots that is wrinkling. Or is there another solution all together. The foam measures about 1.5” larger than the stool pan and the fabric is the same size as the foam. Thanks for your help!

Hi, don't worry been at it for a bit an consider myself a beginner too. It looks like you may need to make a couple of changes to the pattern. I do not think that those wrinkles will stretch out and that vinyl looks thick.

At a glance i'd say your boxing piece looks too long. So is your foam 1.5" larger all the way around? Seems like a lot to me. I'd tend to do about 1/2" larger foam and make the pattern to the size of the seat base with 3/8 seam allowance, boxing length =outside diameter of base. You could maybe cut a new piece of wood 1" bigger all around if the project allows it, see if the wrinkles go away. Gonna look wonderful when you get the fit dialed in.

Thanks for responding and pointing me in the right direction! It’s 3/4” wider on either side so 1-1/2”wider total. It’s a reupholster. And the only vinyl wasn’t wrinkled. I was surprised the wood was so much smaller than the foam. From my understanding, 1/2” wider foam than wood is rule of thumb. Cutting a new base is an easy solution. Thanks again!

Finished this project today. Here are some updates pics. I appreciate your help!

That looks awesome!! Nice job

Looks excellent!

That looks good, glad you got that solved

Well done!

Great work. One thing you can do to eliminate the wrinkles entirely, it’s to make a pattern of your seat bottom. Cut the center out. So it’s about an inch ring plus your seam allowance. Sew it like you did the top.

@Cody, thats cool going to have to try that. Thank you
