It is a colorful illustration!
In case you're ordering this design as wallpaper, the wallpaper has to be attached to the wall from "left to right" (opposed to the usual "top to bottom" way when attaching wallpaper - basically like a huge border print! Just thought I should mention that. Also, since the blue in this design is so intense, I recommend to having this printed on any of the polyester fabrics that Spoonflower offers, i. e. the Silky Faille or the Performance knit. On the natural fabrics, the colors - particularly the blues - will print more dull. A coral reef with octopuses; digitally created combining completely digitally created water and environment with antique octopus illustrations - and, of course, completely seamless! Please also have a look at the 'Fat Quarter' and 'Swatch' sizes (by clicking the corresponding radio button on the right). This design has so much detail, it's pretty much impossible to see it in the (rather blurred!) Spoonflower preview! This design is also available printed on many other products on Cafepress (http://www.cafepress.com/phantasmdesigns/10291664?aid=110890528) as well as on Zazzle (https://www.zazzle.com/bonniephantasm/gifts?cg=196704105398805077&rf=238791567683211815)! The repeat of this design is 36 inches (one yard). It will print seamlessly on fabrics up to 58 inches wide - the wider the fabric, the more 'sky' you will see above the ocean. You can easily test this by selecting any other ,wider fabric by clicking one of the other fabric's radio buttons on the right side. If you were always wondering how different colors print on the various fabrics that Spoonflower offers, please do have a look at my website where I have quite a few comprehensive photos of color swatches printed on various fabrics!
