This is a Counted Cross Stitch Chart from Cross My Heart. 

Entitled 'Sister's Poem' the stitch count is 122 x 140 and the wording is as follows:-

I served the cake,

You poured the tea,

We built a house

Beneath the tree.

In grown-up clothes,

We played the parts;

Secrets told,

We crossed our hearts.

Years went by

Through smiles and tears,

First true loves

And football cheers.

I'll never find a friend so true;

I'll love you, sister,

All life through.
