The above photograph is what I have ended up with, I have made 2 largish sacks on my new sewing machine. We have used Christmas ribbon as the drawstring, although we may change this for cord at a later date. I have also stitched on a snowflake and a few sequins to symbolise the snow that we have had this year. As these sacks are so sturdy they will last forever and I intend to add something new to the decoration every year as a sort of ongoing project to reflect us as a family. Next year I'm thinking that I may sew their names on in a Christmassy way.
This is how the fabric looked a few days ago, It is so heavy and a really stiff fabric, I did bend one needle sewing them, but I'm not that experienced at sewing. If I had more of this fabric it would have made a perfect cape or bodice it really is that thick. I used a simple method to make the bags hemming, sewing a channel for the drawstring then sewing all round the edges.
Here is a photograph of the finished bag with something inside, definitely cord next year I think. I'm pleased that we were able to recycle some old fabric into something that will hopefully become special to the children because lets face it little ones as young as mine are usually only interested in what's inside the sack. It's only when they get older they appreciate all the love you add to these little touches that make Christmas special.
