Sometime ago, I made up a tutorial for a "pincushion and attached scrap bag "and placed it in the tutorial section of Quilt Board - therefore, you can type into the search space pincushion and attached scrap bag and you will see step by step instructions and pictures to make yours. I have made about 85 of these, and those recipients have told me this is their favourite pincushion.
I do not have any extras left over, and it costs about $15 - $20 to mail them to homes in the USA (due to the weight), so not cost effective for me to make them and send them to USA folks, as it would cost you upwards of $40.
