Bluey Muffin Sick Est 2018 Birthday Shirt Design, Cartoon Blue Heeler Style PNG
This bluey muffin sick est shirt PNG is a single cartoon design of a blue heeler-style dog named Muffin wearing a plastic cone collar, with MUFFIN EST 2018 lettering arched above and below him. You receive one PNG file at 300 dpi with a transparent background, ready for sublimation, DTF or print-and-cut work. The artwork is made for shirts, tumblers, mugs and stickers, and it suits a birthday or a pet lover celebration. Muffin is drawn in flat vector style with a bold outline, dark grey and light grey shading, pale grey accents and cream and tan spots on the body. The bold, playful lettering reads clearly at T-shirt size, so the name and year stand out on the front of the garment. Because the design is one layer of colour fills with a clean outline, it is easy to position on a shirt or wrap.
Design breakdown
This is one design, not a bundle. Muffin is a cartoon blue heeler-style dog with a tail, cream and tan spots on the body, and a white plastic cone collar. The MUFFIN, EST and 2018 lettering is set in an arched, collegiate-style layout with a bold outline. The palette uses five colours: white, dark grey, light grey, pale grey and cream/tan. The file is cut in 4 layers, and the cut is medium in difficulty, so fine details such as the collar edges and spot shapes are best cut at 4 inches or larger. The background is white in the source art and the PNG is delivered with a transparent background.
