Pre-shrunk cotton interlining that adds warmth and thermal efficiency to curtains and blinds. At 390gsm, it supports fabrics to hang smoothly while helping single-glazed rooms stay cozy.
Description
Cotton Bumf Interlining – 150cm Wide (Cotton)
Looking for an interlining that adds warmth and structure to your curtains? Our Cotton Bumf is a simple, effective way to improve insulation in single-glazed or cooler rooms, while giving your curtains a fuller, more substantial feel.
This 100% cotton interlining sits between your face fabric and the lining. It’s our go-to option when extra insulation is needed. We are still on the search for an organic version. But until we find one, this Ivory version doesn’t off-gas like some of the white bleached ones we have come across.
What makes it different?
-
Pre-washed in New Zealand, so it won’t shrink when you wash your curtains
-
A heavier weight at 390gsm, compared with most cotton bumfs around 150gsm
-
Provides improved warmth due to the tighter weave
