Does elastic shrink when washed?
It withstands dry cleaning relatively well, as well as machine washing and drying. It shrinks very little, if at all. Nylon elastic is the second best. … Dry-cleaning chemicals will quickly destroy it, and when it’s wet, it loses its stretch.
Is braided elastic good for face masks?
I found the best type of elastic for face masks is 1/4″ (6mm) braid elastic. Braid elastic has ribs running along the length. When you stretch it, it narrows. In my tests, braid elastic held up to stitching and washing better than knit elastic.
Why use smaller needles for ribbing?
This keeps the ribbing firm and makes it more elastic (for the most part there’s not a big difference in elasticity between the common forms of ribbing). Hiatt says “you can hardly use a needle too small” when knitting ribbing for a garment.
What tension should I use for elastic?
Generally elastic works best when stretched 3-8%, with 8% only being used on the smaller parts of the garment as it’s a bit extreme, as remember the more you stretch the elastic the more stitches you are putting on that space of elastic.
