Upholstery Fabrics - Ideas Needed Urgently Please!!  

If the fabric is Divina by...
If the fabric is Divina by Kvadrat it is probably not a fabric that could be described as nubby. The color could be Divina #721, #821, or even #731.

Fabrics for upholstery
i agree with a lot of what has already been suggested. I live in the US and modern fabrics is a great source. If they don't ship internationally, at least gather the names of the modern fabrics they represent. You can often go on to the manufacturers' sites directly and order swatches. Also, if you are looking for a durable fabric, look for the 'rub' count. The higher the number, the greater the durability.

But beware of very high wear ratings
because they usually indicate that the fabric is "contract" grade, or made for office furniture. One hundred percent synthetic fabric often has 100,000 double rubs or higher but you don't want that on good Danish pieces.

I've chosen the Tundra fabric by Kvadrat in a beautiful blue green color. TOTALLY AWESOME! Tundra 2/887
Thanks,

Pretty.
887:

yup that's it
And I have a blanket size sample to drape an area in my home which helps tremendously. Those small swatches are hard to visualize. It looks so much better in person.

Grete Jalk vs. Thrive Kennedy
I've recently purchased a Grete Jalk chair. I'm new to MCM and still learning... and upon taking this home I realize that the cushions have been replaced.
While they are thick and comfortable, they are also too large for the seat and have a crammed in sort of look which doesn't lend itself well to the clean lines of the chair.
Should I have the cushions replaced?
Also, I want to reupholster the cushions because the fabric (which is not original) really clashes with our living room decor. After emailing with Thrive, I discovered that while they won't sell their fabric by the yard, they will sell replacement covers for the Kennedy chair for $150. But on their website they don't offer the dimensions for the cushions... just for the chair. Does anyone have a Kennedy chair or know the dimensions of the cushions?

Yes, you should replace the cushions
if they're too thick and don't look right.
I looked at the Thrive site. I have not seen their fabrics in person but I would bet from looking at them online that they're not especially great quality. They don't list fiber content, let alone wear ratings.
A Grete Jalk chair deserves the best. Box cushions aren't hard to make. Conventional upholsterers make them all the time. You just need to get the right fabric, which can be harder to do from a conventional upholsterer because they usually order from companies that make whatever the mainstream market dictates.
However, it's easy to get the good stuff on Ebay, Modern-Fabrics.com and some other places, you just have to know what you're looking for. You can start by ordering swatches from Maharam and Knoll. You can't go wrong with the wools in the Kvadrat line of Maharam fabrics; look at Hallingdal, Tonus, and Tonica for starters. Knoll has a lot of office type fabrics but they do have some nice wools too. Look around the internet for bargains on these; you only need about 2 yards and there are a lot of remnants out there.
Maharam, Knoll, and all the other fabric manufacturers will give complete fiber content info, wear ratings, cleaning methods, and a lot of other information about their fabrics. Most furniture companies do not supply this information.
And lastly, I would never give any business to a company that sells knockoffs of others' designs, even if they did use quality fabric and listed the specs for it.

Hello, I have a Grete Jalk chair the same as the one in the picture above. I need a good upholsterer / someone who knows both how to make the cushions and how to do the strapping for underneath the cushions. I'd be happy to work with Spanky if possible and would also be interested in good sources in the Bay Area of California.
