a gauze fabric with an extremely fine texture

filaments from a web that was spun by a spider

characterized by unusual lightness and delicacy; "this smallest and most ethereal of birds"; "gossamer shading through his playing"

so thin as to transmit light; "a hat with a diaphanous veil"; "filmy wings of a moth"; "gauzy clouds of dandelion down"; "gossamer cobwebs"; "sheer silk stockings"; "transparent chiffon"; "vaporous silks"
