Using a Bobbel

Hello, fellow crafters!  I’ve been wondering: If I start working with a Bobbel but then have to unravel my piece again, how do I get the yarn back into the Bobbel? It’s probably not possible, so up to now I’ve always wound it into an extra ball. But that’s hard to work with. So I thought—there are so many clever people out there who might have already come up with a solution. I’d really appreciate any suggestions. Thanks! 

You can wind the yarn around a cardboard tube (from toilet paper). It might even fit in the middle of the yarn cake.

I just pragmatically wrap it around the whole yarn cake :-)

Thanks, I’ll give that a try. That was nice of you to reply so quickly!

Oh, of course! Why make it easy when you can make it hard! I guess I sometimes overcomplicate things.
Good thing I asked for help! Thanks
