Jam Jar Fun

Jam jars are very useful they can be used to store many thing tie and time again. We have one jam jar that has a replacement plastic screw top. It looks very pretty but has a sharp edge to it so when you try and unscrew it the potential of cutting you hand is on if it needs some force to open. this is what happened today. The lid was jarred and the extra force that was needed cause a cut on my finger. Next time it will be opened with a tea towel to avoid the sharp edges.
