Lasagne beds - looking for advice

Hi I made some lasagna beds last autumn. They have worked well have excellent crop of squashes on them now. I started with cardboard, bike boxes from Halfords, well watered, then grass clippings,beg from neighbours if you don't have enough. Then brown layer, general garden prunings and some manure if you can get hold of it, then more grass clippings. Just keep layering. I did three layers but I will probably have to add more this year as it has rotted down. I covered it with black permeable membrane over the winter and have grown the squashes through that this year.
Hope this helps

V similar to the advice above. When I started out and didn't have any compost, I ordered some spent mushroom compost, used free manure and bark chippings from site and grass clippings, newspaper and cardboard.  It worked...

I have just started a lasagne bed on the old strawberry bed which needs filling up. (pic in my diary) So far I have a layer of cardboard, layer of pea and bean foliage, annual weeds and kitchen waste. When I get enough I will cover with cardboard or newspaper and compost if I have any, or council soil improver if I can get it. Then I am just going to leave it for the winter. I might cover it with weed fabric sheeting and plant through in the spring.
This is the third bed I have done like this and it is a good way of filling them up.
I'm not sure how organic cardboard and newspaper is though.
