There are objects round our house and garden that remind me to pray for people. Outdoors we have Siberian iris, given to us by the Dominican friar who blessed our wedding, Aidan Deane. A couple of years ago we were able to give a crown to the Dominicans in Edinburgh for the garden around their new chapel.
I like Bro Guy Consolmagno’s comment, linking such things to our pre-Christian roots:
Our knick-knacks define home to us; they are, echoing the practice of ancient Rome, our ‘household gods.’ 
I recently had an exchange in verse with Frank Solanki about this. He wrote:
Without you here
This ain’t a home
Not even a house
They’re just walls
(See more of Frank’s work here: https://franksolanki.wordpress.com/ )
My reply may tell you that my mind is more cluttered than Frank’s – or is it just my house?
Walls and crannies.
But now, reflect, all these years on,
Each room still breathes my girls, my son,
Though from our home they all have gone.
Photos stand among my books,
Seaside shells in little nooks;
Serving spoons on kitchen wall,
And, dear friend, that is not all.
Stored for years in the loft above
Are things they need not but can’t shove:
Toys that whisper words of love.
What objects might the holy family have kept around the house? I expect the Magi’s gold was used to set up home in Egypt. Is that where they are in this picture? Mary has a rose around the window to help make the house a home.
We can pray to the Holy Family, that our home may be a safe Ark for all our family:
Jesus, Mary and Joseph, I give you my heart and my soul, I give you my family and loved ones.
