What is it good for?
It is actually a bag which is stuffed with wood shavings to make a compact and round thingamajig to put into coat shoulders or set sleeves for ironing. Doesn't sound impressive?
Well, my mum used it once and now wants her own! It really helps to get rid of wrinkles in coat sleeves as the fabric is ironed in the form that it should stay and you can use the warm wet heat (that will generate strange visits to my blog, I can see it coming! ^^) to move the fabric and reduce wrinkles from sewing!
What does it cost?
After struggling to find a German word for Tailor's ham (hint: Schneiderschinken doesn't work), I found one on amazon for 6 Euros including shipping. You could also make one yourself, but for that cost, why bother with the mess?
Who needs this?
Everyone and their mom! It helps to make garments, it helps to iron (bought) garments, it reduces trouble to iron blouses (you know, the booby-does-not-stay-flat-part?!) and it is even rather cheap. Go ahead and get one already!
