Not sure where this quarantining of parcels started up. Thee is no need - keeps being said in all official advice. Wash your hands after bringing parcel into home, wash your hands after taking off the cardboard or whatever packing and disposing of that in normal bin - and that is all there is.
Why were you washing your hands each time you did some knitting? Unless you have lots of people in your home most of the time .
Do think people are misunderstanding so much about this (and other) virus. Do wonder how many illnesses are going to spreading due to this excess of disinfectant and bleaching that has been going on.
Send your lovely gift and let them enjoy it.
