A Crochet Pattern For A Throw With Big Overlay Mosaic Crochet Granny Squares
Step into a world of texture, dimension, and visual intrigue with the Depth Perception Throw — a bold and captivating blanket pattern designed using the overlay mosaic crochet technique. Perfect for crocheters who love rich textures and geometric depth, this project blends structure with creativity to stunning effect.
Written using US crochet terms, this pattern features squares worked in the round, from the center outward, with identical instructions on each side. You’ll alternate two contrasting yarn colors (C1 and C2) to bring out the dramatic 3D effect that makes this throw so visually striking.
This mosaic design uses:
Single crochets (SC) in the back loop only for the background texture.
Drop-down double crochets (DC) worked into the front loop two rounds below to create the raised overlay pattern.
With each square, you’ll follow one set of side instructions, repeated four times per round, separated by chain-2 corners. A color-coded chart is included to help you visualize each motif, and you’ll find both written and visual guidance to make the process as smooth as possible.
The construction method allows for full flexibility:
Customize the size by stopping early on square rounds or continuing for a bolder motif.
Make the throw larger by creating more squares and arranging them however you like.
In the sample shown, 9 squares were used:
4 squares follow Square #1 instructions
5 squares follow Square #2 instructions
Arranged in three rows: 2-1-2 (top), 1-2-1 (middle), 2-1-2 (bottom)
Finished dimensions are approximately 175 x 175 cm using the suggested yarn and hook size, but your final size can vary depending on your yarn choice and tension.
This pattern was designed with a wool/acrylic blend yarn to balance softness and stitch definition, but any yarn with good contrast between colors will work beautifully.
Whether you’re drawn to the satisfying structure of overlay mosaic crochet or just love a throw that makes a statement, the Depth Perception Throw is the perfect balance of precision and personality.
A printable version is also included for your convenience.
