Have an old net curtain, suspended between 2 chairs, with 6 freaking kilos of blackberries, dribbling away.. I usually get around a pint per kilo of juice (being disciplined, adding no water and allowing no squeezing) which doubles with added sugar, so a dozen 1lb jars to supplement the half dozen jars of redcurrant jelly. Years ago, I used to make well over 100 llbs of various jellies...but honestly, the hours and hours and hours of picking put me off, so when the offspring no longer clamoured for blackcurrant cordials, I binned off the whole earthmother thing in some relief. Only a scary fear of starvation (and not really wanting to eat anymore chocolate spread on my toast) has encouraged me to get my old picking basket out (I hang it round my neck to use both hands for picking).
I managed to rescue around 8 or so kilos of filberts, but only by chopping down the whole tree...but donated to eldest as teeth (lack of) means nuts are a challenge too far and I really cba doing nutmilk stuff.
