Times are strange right now, aren’t they? I try not to dwell too much on the current situation on this blog or my social media, I think crochet should be a comfort. And, by extension, this blog should be too. But, that doesn’t mean it isn’t on my mind. You may have noticed there’s been an increase in cosy projects for your home and rainbow-themed crafts popping up here. I’ve been sharing projects like the Anthropologie Inspired Long Pillow, Little Rainbow Cloud and of course, the Bobble Stripe Blanket CAL. Today’s guest post from Katie at Crafticated Crochet combines both. This radiant rainbow crochet blanket not only brings some brightness and joy but also some much needed comfort.

“As this is a guest post, Bella Coco Crochet is unable to answer any queries. If you have a question, please contact the designer directly and they will be happy to help you.”

Katie says, “I originally designed this pattern as a commission for one of my friends. The pattern is very relaxing as it is a repeating row. This project is great for anyone who has mastered the basic stitches of crochet and is looking for a larger scale project, or anyone that just wants a relaxing project which will really make a statement in your home, or a great gift.

Materials & Tools

Hook: 5.5 mm or 6 mm

Yarn: Paintbox Simply Aran in (A) Rose Red, (B) Blood Orange, (C) Buttercup Yellow, (D) Grass Green, (E) Kingfisher Blue, (F) Pansy Purple

3 x 100g balls of each colour will create a crochet blanket 4 ½ ft x 6 ft

Measurements & Gauge

Gauge: 10cm x 10cm = 16 stitches and 16 rows

The finished size of this blanket (4 ½ ft x 6 ft) using the recommended materials and gauge means it would be perfect as a sofa throw, or for a single, or even double, bed.

Notes

A little note on colour changes, when I got to the end of a row and wanted to change colour, I simply hooked the new colour through to create the loop on my hook, pulled the previous colour tight, cut the previous colour (leaving a tail) and then tied the yarn ends together before sewing both ends in securely.

This blanket uses moss stitch

Row 2: ch1, turn, dc in chain space from previous row, *ch1, skip a chain, dc in next stitch* repeat to end of row.

At end of each row, you should have two dcs next to each other, ensure your final dc goes between these two dcs, this will ensure you keep the right number of stitches and your edges are straight.
