This one comes in part from a suggestion from @limpid hound, recently new member to the Discord. Thanks, and welcome!
We've seen some really nice and interesting bits of merchandise from Dreamcatcher over the years, from mood lights to lightsticks in coffin boxes to all kinds of t-shirts, to jerseys and more. But if you had to create something that was different, random, or interesting that you think might sell, what would you create for the group? Hoping to hear your ideas!

I know they have had one in their Odd eye album, but it would be cool if they had like their own dreamcatcher dreamcatcher you could just buy
abstract quail
Im all about games, one made by them like Dream Quest but maybe more complicated would be so cool!
weak depot
More magnets! I love my magnets
frozen saddle
Special project of mine actually.
I'd love to see phone cases based on their album art or just member versions.
slate condor
plushies would be cool, something like their representative animals.
i already imagine a pandami plushie next to my massive panda one i've been having since i was a little girl

I'm still going for gaming merchandise. Mouse pads, keyboards, headphones, you name it for DC themed merch. I love the official colours and I think both the logos and the colours would fit extremely well into a gaming setup.
vagrant geyser
Photocard sleeves with members on the back. Useful for those with clear binder pages though
dire egret
Baseball jerseys, I wanted them badly last tour lol
Also official sheet music
maiden wren
Agreed with plushies, I'm also really like a blanket

I really want an official mini Dreamcatcher lightstick keychain. I have the Loona one and it’s so cool, actually used it at a recent OEC concert. Also, Celly has so much opportunity in the way of merch. It can be adapted to any concept as the stickers already shows he has different forms. Maybe the Reason Insomnia guy as well 
. So much can be done with that!

I second the plushies and the Mongmongie keychain.
