She tasted some and found them to be quite sweet indeed. Most of them had already turned purple and were ripe and needed to be picked quickly.

Xiangnan took the grapes back and gave half to Aunt Zhou's family: "Help me eat the grapes, I want the grape skins."

Zhang Dalei's wife laughed and said, "Xiangnan, are you trying to make me laugh to death? Who would treat someone to grapes just for the skins?"

Xiangnan chuckled: "I really need the grape skins for something, remember to save them for me."

Take it back to Xiangnan and ask everyone to eat it together. The more the better, but make sure to leave the skin.

She ate some and couldn't eat anymore, so she just peeled the skin and left the meat in the bowl. Later when she had time, she would use it to make grape ice cream and grape fruit salad.

Huo Qing helped her pick a basket of indigo grass. Xiangnan washed them all and put them on the stove to cook, and did the same with the grape skins.

Boil for half an hour, then turn off the heat. Then boil for another half an hour, then turn off the heat. Filter the boiled water with a cloth.

These aunts who filtered the soy milk were very skilled at it and soon produced two buckets of dye.

After letting them cool down, take two small basins from Xiangnan, pour out a little dye in each, mix them in a 1:1 ratio, put a piece of white Dacron cloth in, and heat on low heat.

After the white cloth is completely dyed, take a small basin, fill it half with water, pour in the alum bought in the county town today, wait for it to melt, and then put the colored cloth in.

Alum, color fixing, soft water, and auxiliary dyeing aids are very useful things for dyeing cloth.

After the cloth was completely soaked in water and changed color, it was taken out and dried. The color was not the light blue with a little pink that Xiangnan wanted.
