Lots of layers!
Both of mine are wrigglers and blanket-thrower-offer-ers lol The other thing to think about is how many layers you put UNDER them - ie sheets and what not on the mattress itself.
Layers over the top are limited in effectiveness by how much heat is lost through the base. So a sheet, a couple of thin but dense bankets under the sheet will help in retaining the heat you can trap by blankets or layering.
I like breathability - so wool, natural fibres, will always be better than polyesters that can cause sweating, which when moisture is trapped, makes one colder rather than warmer.
