Any model terrain supply deals

[PJ]

Are the supplies specific to DnD or is it just raw materials that you use to make things for DnD?  Do you have any links to the types of things you are looking for?

Things like this Doors and windows templates, Different types of flocking, or Texture rolling pins (just a few for example). It doesn't need to be specific to DnD, even silicone molds would be nice to find at a cheap price. I like crafting as well as woodworking and it's nice to make stuff up sell especially when work gets slow. I've been watching some different YouTube channels that make stuff for tabletop gaming (wargaming, DnD, etc) as well as making Halloween props.

It looks kind of similar to the stuff people do with model trains.  When they build like a city around the track, I wonder if any stores sell things marketing to those people but would also be useful for you?

May be a really bad idea but for like the floor tiles I see people make can you use expanding foam in a mold?

Amazon has a craft section for promo codes but it only has 3 codes in it right now and they are all for colored markers.

Have you ever tried going to Michaels?  They usually (corona might have this changed for now) have a 40% off single item coupon in their sales flyers.
