“Carousel” is an in-the-round overlay mosaic pattern that can be extended to anything your heart desires.

This is an overlay mosaic pattern worked in US terminology.

You will need to know the basics of mosaic crochet but there are tons of videos for beginners on YouTube.

Mosaic crochet is a dense crochet, no “holes” so is ideal for blankets, rugs, runners, cushions, etc.

You can use a variegated/print/cake yarn and allow the yarn to change colour on its own or you can use two separate colours to create a contrast in the pattern.
