Women were working fields and were working with farm animals too. They did not done work that required physical strength unless they had no choice, but that does not mean they did not "worked fields".

Second, work being split by gender does not matter here. Women are, by definition, people too. And weaving, sewing, candles crafting were all literal necessity. A weaving woman would sell or exchange results of her work if she had an excess of it. They were not bored SAHM hobbies they way they would be now. This was economic activity just like any other.
