DemiCon 34 themed shirts and other merch

DemiCon 34 hoodie.

Each year we have a DMSFFS Table where congoers can buy DemiCon and DMSFFS swag.

At the DMSFFS Table we have things like badge holders, cups, bags, and other cool stuff, but the pandemic changed some things. Our selection is smaller and we have shifted more of our merchandise to online sales. Part of this is due to long time suppliers going out of business and part of it is to reduce up front costs.

We plan to have a very limited number of t-shirts available for purchase at the con, but the online store has a wide variety of shirt styles (larger sizes, tank tops, extra long, long sleave, etc.) as well as some items like mugs, stickers and notebooks.
