I used the good old chopsticks and glue-gun method for these. I didn't try too hard to replicate any specific wands, although I did take inspiration from them. I used some acrylic paint and then went over with some metallic water colors for extra shine. This was a fun project, but it took a couple of days because I had to wait for each layer to dry.
The letters were easy enough to address, and I melted some candle wax with a red crayon for the seal on the back. The tricky part was using invisible thread to attach them to the fireplace. Invisible thread is... not surprisingly... pretty difficult to see.
OK - technically these aren't all from Honeyduke's in the book but it was fun to have some themed candy. The snitches were a little tricky, it was hard to get the sparkle paper to stick to the foil... I had to use a combo of glue and tape (don't look too closely). ;)
Saved up a few tiny liquor bottles to catch memories. The pensive is just a plastic bowl that I painted with silver paint and glitter. On the left there's an old mood ring that I painted to look like the Gaunt ring.

S.P.E.W was on of my favorite parts of the book... and I already had the hats/socks, so this was pretty easy to put together.
There were a few other crafts that I didn't get pictures of but overall it was fun to really get into trying to create a Hogwarts feel for the party.
