When I’m designing a new crochet baby blanket I really try to think about what most people want for babies. I’ve designed so many over the years and a recurring theme has emerged – simple and classic. Even if the blanket is really colourful I try and balance that with a really simple stitch texture to balance it out. Conversely if it’s a single block of colour then I use a bit more texture and detail in the stitch and construction and this always seems to be a winner. My most popular designs have always been baby blankets in neutral colours that feel modern and not fussy but that nod towards the traditional. I hope The Oyster Shell Blanket is one to add to that simple and classic collection.

I’ve been using a really bright and fun colour palette recently and I felt like it was time to calm it down with this latest design. The stitches I’ve used are my take on cluster stitches and the chain spaces give a delicate fretwork style to the blanket to give it a lovely drape so it’s perfect for a summer baby.

Yarn

I designed the blanket in Deramores Studio Baby DK – Oyster 005. The entire blanket only took three balls of yarn so is a really budget friendly make.

The yarn is 100% acrylic, 270m/100g and there are 15 beautiful shades to choose from.

The fabulous folks at Deramores have put together a yarn pack (which also includes the free pattern PDF) so if you fancy it in the Oyster shade then follow the link below:

Finding the right yarn for your projects can be tricky sometimes and depends on so many things like fibre content, yarn weight, budget, colour choices and more. I’ve put together a guide for the best yarn for crochet blankets to help you discover the things I’ve learnt over the years as both a designer and maker that help me choose the perfect one.

Tension and Sizing

The finished blanket measures 80cm by 96cm.

Tension of main pattern – 3 sets of clusters and 5 rows = 10cm x 10cm

In UK Terms:

For a 4dtr cluster stitch (4dtr-Cl) begin as if to double treble crochet in next stitch, but don’t complete the stitch and leave two loops on the hook. Repeat this again, crocheting as if to make a double treble crochet but don’t complete the stitch and leave three loops on the hook. Continue to do this, working into the same stitch, until there are 5 loops on the hook. Yarn over, pull through all 5 loops on the hook.

A 2tr-Cl is worked in the same way but just completing the stitch after 2 stitches instead.
