The nib won't fit since it is a very different type. It is clipped to the feed instead of being set in the section the way the other nibs are set. That said, the Petit is an excellent pen to use. I can try to ask my family and take some pictures to show you that they do not fit if you want.
Oh that's so nice of you, but not, not necessary. I can see that they don't, and I can believe it - the idea of getting the Petits for my nieces is another thing entirely and has nothing to do with these nibs - I just thought they were affordable enough that if the girls don't love them, fine, and cute enough to make them try them at least once.
No, my crazy search for a nib goes on. I can make another stab at making a nib from soda bottle plastic - last one dint' work, but practice may make - well, better. Or I can try to use a feather shaft to see if that will make a useable nib, or I can dig around whatever other sorts of nibs I find in random places to see if one can be made to work well enough...
This nib thing is not really about getting this pen to work so much as it is seeing what I can manage. Getting a Pilot nib from Pilot would have been very nice, they don't sell them that way, so brain goes into overdrive. Maybe crazy, but fairly harmless.
But I can' t get over how nice you are, willing to take photos and everything to show me - that's really above and beyond. I appreciate it, but I already believe you, so I will just thank you most sincerely, and keep looking at the pens that might have a fitting nib for this project, and only at the Petits and Varsity and so forth for other, different things.
Thanks a ton because your willingness to help me really made my evening!
