Apologies for the delay in responding. I've been slammed at work, and also experience a medical opportunity.
....That's amazing that you found that in a store. And you have an impressive collection. Love the memory vials. Also, what is that crumpled page from? .....
Ruari - That's a "Basilisk page" - the one Hermione has in CoS. My copy was made by Juno - I sure wish I had her talent!
...That fang inspires me to create my own.....I'm pretty sure the basilisk fang was actually resin.....
poisonivyism - I don't know much about or have the equipment to make casts. I do have saws and sandpaper though .
BTW - I made another that looks more like the one being displayed:
This is made of aspen wood from Lowes, roughed-out with a bad saw and then drum sanded. I used some walnut stain on the sides and some mahogony stain on the "broke-off" end.
