Below are links to all of my print on demand stores and a bit of info on what you can find in each shop.  Each store has unique products! Check the shops regularly for sales!
My main shop! I've been adding products to it for years and it keeps getting bigger! Lots of great home decor products, furniture, and outdoor products! (This is an affiliate link. I receive compensation for any purchase made through this link)
Same product selection as my main Society6 shop, but fractal art only!  There's some great psychedelic stuff here! ​(This is an affiliate link. I receive compensation for any purchase made through this link)
I started this shop to have a place to sell art specifically designed for leggings. The art here is mostly simple designs and seamless patterns. ​(This is an affiliate link. I receive compensation for any purchase made through this link)
Digital prints and graphics, original art (ACEOS) and jewelry coming soon!
I follow back and promote other Etsy sellers regularly!
One of my newest shops, they have a nice selection of products! I'm particularly fond of the plates, pencil tins, and deck chairs!
Tons of funky products, mandalas, fractals, and generally wacky abstract art. Everything from cookies to computer mice, and shoes to wall tapestry! They even have nail decals! 
This shop sells leggings only, however, if you want anything printed on a different product, Zazzle will let you transfer the design!
More mandalas, fractals, and seamless patters. RedBubble has great clothing options! I personally recommend the graphic t-shirt dresses, they are unbelievably comfortable. They're tote bags are also very sturdy! 
Another of my newer shops, I have a huge amount of trippy artwork for sale here! RageOn has great clothing options, perfect for music festivals! Their hoodies, "onesies," and swim shorts are very popular.
ArtSadd has a huge array of products choose from, (probably the largest selection I've seen from a print on demand site!) and I'm adding more products every week! The only site I've found so far that sells UMBRELLAS! :D They have those cute phone holders too!
