I purchased weekly pill containers fron the dollar store. The bobbins fit just fine and at $1 each you can have one for each color family.

Both machines use the same bobbin, so what difference does it make?

Terribly sorry to have made an error. Will you ever forgive me? I wasn't aware there was an 820. I thought it was 810 and 830 and now the 880.

Yes there is both an 820 and 830.

Go to the dollar store and look for the little sponge thingies that you put between your toes when you do a pedicure. They have wide slits in them for your toes and work wonderfully to hold bobbins and since they are sponge type plastic, they will "stretch" to accommodate different sizes. Each one holds five bobbins.

go to Harbor Freight get a magnetic parts holder that men use, and just toss em in

I buy the pony tail holders they make for little girls that are made of stretch terry loops. You get a gazillion for a dollar at dollar stores, put one around the bobbin to secure the thread ends, then I just put different thread types in different bowls, but you could make your own bags if you like.

I don't have a Bernina, but my Kenmore's metallic bobbins happily live in a magnetic bobbin holder. If the Bernina has computerized parts would slightly magnetized bobbins mess it up? If not, this might work for you.

You can also go to the sports department at Walmart and buy fishing tackle boxes which are divided into sections. I have 3 which are about 5 by5 and they hold many, many bobbin. I cut a dowel to string the bobbins on before I lay them into the compartments.
