This interlocking crochet pattern is part of the special bonus chapter that comes with my book, Reversible Crochet Sweaters (US publication date: November 4th, 2025). The bonus chapter ebook is professionally formatted in the same layout as the book and consists of two brand new reversible crochet patterns: the Stained Glass Jumper and the Stained Glass Scarf. Everyone who pre-orders the paperback version of my book receives the bonus chapter for free! Please note that the Stained Glass patterns are not currently available for individual purchase and can only be obtained by pre-ordering my book.

DESCRIPTION
The Stained Glass Jumper reimagines one of crochet’s most iconic stitches, the granny stitch, in a way that feels both nostalgic and refreshingly modern. Layers of color and texture form a reversible fabric full of movement and depth: on one side, a crisp mesh overlay creates a grid of “stained glass” panes; on the other, the familiar granny clusters shine through in shifting tones.

This pattern comes with two style options: a long-sleeved jumper for cooler months and a short-sleeved tee for warmer weather. You choose which one to make!

The construction is simple, the fabric beautifully drapey, and the process surprisingly intuitive once you get into the rhythm. It’s a project that celebrates color, comfort, and versatility in equal measure.

And if you can’t get enough of the effect, don’t miss the matching Stained Glass Scarf for a perfectly coordinated finish.
