J ...... is for

 A difficult one this week,

 but I eventually managed to find a stitch which began with the letter 'J'

It's from the Canvas-work family of stitches and its called 

the 'Jacquard' stitch 

and with it I stitched a 

Jelly 

 I embroidered the pattern which is done diagonally onto canvas,

 then cut it out and stitched it onto the background tag

... a closer view of the stitch
which is worked using a variegated peach thread in alternating rows of long and short stitches.
