This spiral or cross thread is covered by the spider with thousands of tiny drops of a very sticky substance.

蜘蛛又在这些螺旋或交叉横丝上涂抹了数以千计的非常粘稠的物质。

Such that the cross thread called the weft passed above or below the thread.

这样，称为纬线的交叉线从线的上方或下方穿过。

There are two sets, crossing each other and going up and down as they cross, just as you see your mother crossing the threads of wool when she darns your stockings.

细线有横竖两组, 交叉排成十字形, 就像妈妈给你补袜子的时候, 把羊毛线交叉排列起来一样。
