Prostrations stop with Vespers on Friday evening and start again with Vespers on Sunday evening.
The Jordanville Prayer Book is helpful for when to do prostrations at private home prayer
Even more helpful in this regard is the Old Rite Prayer Book
The Old-Orthodox Prayer Book certainly clarifies the prostration schedule for private morning and evening prayers very well.
