Re the large print books, you can get them from your local library (If it is still open) or as a PP said on a kindle you can resize it.
You can also get audio books from the library. I have an Alexa that can read my kindle to me.
Re making butter.
The simplest but time consuming and gives you a work out, is to pour the cream into a clean jam jar screw the lid on tightly and shake it.
And keep shaking it, and keep shaking it, call the kids in to shake it while you have a cup of tea.
Realise you have put too much cream in one jar so separate it into two jars and keep shaking.
Make it a competition between you and the children to keep shaking. Eventually you end up with butter and buttermilk.
I have never actually used this method, that's what food processors are for.
My grandmother would apparently use the top of the milk, divided into three for her children to make butter by rolling the jars on the rug - it kept them busy for an hour or so.
