|When you alter garments|
the fabric choice is very important.
One knitter wrote: I've used burn tests many times. It is invaluable. I've used it a lot to test knitting yarns where I've lost/misplaced the label. It's really helpful to know whether the yarn is wool or not!
An experiences stitcher wrote: Using a shot glass with a tablespoon of bleach is also a good way to test if a fabric is a purely proteinous fibre -- silk or wool (as opposed to a plant fibre such as cotton or linen).
|I do not sew this well.|
The trouble comes when fibres are blends. It's much more difficult to tell blends with a burn test, at least that has been my experience.
I thought this comment was also informative if you sew for charities: I belong to a quilt group and I am the Tester. We get donated fabric and we also make items to be donated. Some places only will take things made out of 100% cotton, for instance Ronald McDonald House. We have made pillowcases for them several times, and I test the fabric for them so as to make sure it is 100% cotton.
The photos I have used here all come from the Threads Magazine pages and were submitted by various readers of that magasine. That website is a valuable resource if you sew.
