Frequently Asked Questions

Where do you get your cork?
We import the cork you see here from a manufacturer in Portugal.

Why cork?
Cork is an ecofriendly alternative to leather that is natural, sustainable, vegan, and PETA certified. The cork bark is peeled from the tree by skilled labourmen without harming the tree. The same tree can be reharvested every 9 years for up to 300! Cork leather is as strong as it's animal counterpart, water resistant and has naturally occurring antibacterial & antimildew properties.

Is it durable?
The cork at MM Cork has been treated to be stain resistant (Scotch Guard) and has had a UV treatment and an abrasion treatment. They have been tested in external labs for abrasion (martindale test), UV resistance, Vamp Flex,and Ignition (fire).

Does the dye run when wet?

Does cork have a backing?
Yes, it is attached to a soft, flexible cotton woven fabric backing.

Can you leave the edges "raw"?
Yes you can.

Is it easy to sew?
Oh my word YES!!!! It really is a wonderful substrate to sew with, easier than vinyl or leather, and more forgiving.

What foot/needle do you use?
Personally I use a teflon foot, but I know many people have great success with their regular feet. As for needle, I use titanium 90/16 on my industrial, and Microtex 90/14 on my domestic - NOTE: EVERY machine behaves differently, find what's right for your project and your machine.

If it is folded, does it crease?
Yes it will, this is why we send it to you rolled, rather than folded. The folds will come out, but it takes time and patience.  To remove creases, try wetting the cork backing and hanging it to dry, or pressing it under heavy books.
Does it need to be interfaced?
If you feel the need for more structure than the cork fabric has naturally, please glue or sew baste the interfacing rather than ironing it.  High heat can damage the adhesive layer, causing premature wear, peeling or cracking of the cork layer.

Can you iron it?
Not recommended, high heat can damage the adhesives and cause cracking and/or peeling. 

Does it stand up to machine embroidery?

Here’s a great post on CLEANING your cork bag:
Can I scotch guard the cork?
No need to - it has already been done at the factory! I’m not sure of the chemical composition difference between the one we would buy and the industrial type so please either cover the cork overlays OR try on a swatch first.
