Sometimes you can find them in places like this
or even here (SO embarrasing!!)
To avoid these unfortunate situations in the future I have being searching for suitable options.
I could make a strawberry pincusion like this one,
which I found on Martha Stewart's homepage.
But I think that I will be better off with a needlebook, like the one from the book Tilda's House.
It will be perfect for when I bring a needlework in my bag, and I will avoid being pricked in my finger when ever I pick up my purse from the bag...
