I've seen something like that made for gardeners using a 5 gallon bucket. Emblibrary has one with pocket inside and out. Lots of room for embroidery, too. I hope this is what you were thinking.
Thats it. Thank you. I am going to use a smaller bucket, like an ice cream bucket for all my sewing needs when going to sewing group. thanks again.
Glad I could help. Sounds like a great project. Please post a picture of it when you are finished. Nancy
Perhaps this one from All Sorts of Embroidery?
I don't know exactly what you are looking for, but on this site are many pattern for all kind of sewing stuff. so perhaps you can find something here.
