Thanks to Nanci Keatley who has just told me about her 'pocket oratories'. Each one is a miniature hand-held iconostasis, which can be kept in your wallet or purse and is a focus for prayer. If you pause in the day, perhaps to pray the Office or the Rosary, this can be an excellent portable visual aid. Unbutton it and open it up and you can focus on the images in the palm of your hand as you pray. What a great idea this is! They are available here.
This one has icons from the Little Oratory book as well as the Sacred Heart.
