Creases in k'laf
I recently checked through a Torah that had been rescued from Germany just before Kristallnacht in a suitcase. It is going to require some considerable restoration and means a great deal to the family and congregation that it is loaned to. However, four or five amudim have very bad moisture creases. I have been in touch with the British Library regarding parchment restoration and also chatted with a sofer colleague but was wondering whether anyone on the forum has practical experience of dealing with this. I don't want to replace the yeriot if I can help it because of the historical nature of the Torah - it has lots of marvellous kabbalistic taggin and special otoyot. Also, I would be interested in the view on kashrut if the crease is particularly heavy and obscuring the letters even if they are a) there and b) complete when the creases is pulled back, as I've only dealt in the past with relatively minor creasing where the letter was still guf echad or where addition of ink made it so.
