Working with gauze isn’t difficult but here are a few tips.
Gauze is pretty slippery so cut with sharpened scissors or a rotary cutter with a new blade.
Use sharp pins when pinning, and mark your notches instead of cutting since cuts in this fabric can be hard to see.
When sewing, use a longer stitch length to avoid puckering.
Finish the seams with a serger, zigzag stitch, or fray check to keep the fabric from unraveling.
Cotton gauze should be hand washed in cold water, but can also be washed in a machine on delicate to avoid shrinking and damage. Hang dry or tumble dry with no heat.
