kudos to you, for being willing to admit it.
Many do it but would never "come out"!
As you mentioned not all plastic bobbins are the same.
It's important too to use the Janome bobbins ... for all they cost, it's makes more sense to use the "right" ones and avoid the aggravation created by the wrong ones!
