The stitching itself if not difficult. You will need to finish it into a stocking. The chart does not provide finishing instructions but I'm sure you can find some good advise on the internet. You will also need to attach the embellishments if you choose to purchase them - but that is easy.
When stitched on 18 count fabric the chart says the cut size of the fabric is 18" x 24". The stockings are good sized when finished.
