Free Crochet Lap Blanket Pattern : Princess of Diamonds

I was asked by someone in the café where I volunteer at a craft club if I had a lap blanket crochet pattern.  I happened to be working on my Queen of Diamonds poncho at the time (it was over my legs as I was crocheting) and thought how great the design would look for a blanket!  I knew I had yarn in my stash I could use, so it was a no-brainer to use the same technique to create a lap blanket! 

This lap blanket is an easy project, doesn’t use much yarn and is suitable for lots of people of all different ages (think the elderly, children, travellers or for anyone who loves to snuggle in a cozy blanket).  If you’re looking for a last-minute gift, this blanket would be perfect!

My latest blanket pattern begins with a granny square which is transformed into a diamond at the centre before continuing to be worked as a granny square. The scalloped border adds elegance as well as giving the lap blanket a professional finish.

I’ve named the pattern ‘Princess of Diamonds’ – it seemed appropriate as it was inspired by my Queen of Diamonds poncho!

How the lap blanket crochet pattern is worked

Section 1 of the pattern is a classic granny square.  I use chain 4 and slip stitch into the first chain to form a ring to work into (if you use a magic circle that is fine too). 

Section 2 works on decreasing the sides of the granny square to change the shape to a diamond.

Section 3 works two rounds to set up before the granny square continues.

After trying several borders, I opted for scallops.  I think it adds a fab finish to the blanket!  A round of single crochet (US)/double crochet (UK) is worked first to set up ready to crochet the scallop border.

I wanted to add here that if you would like to make yours bigger than a lap blanket, continue with round 6 of section 3 until you reach your desired size and then work the border.

I’ve used the same technique in my Countess of Diamonds shrug pattern which gives the garment a unique twist.

Yarn

I used Woolcraft’s Cotton Candy yarn for this lap blanket – the same yarn I used for my poncho pattern.

I bought this yarn in the two colourways when it was on sale quite a while ago and was fed up seeing it sitting there in my stash!  If you can still get hold of it, it is great value for money.  It’s so soft and perfect for blankets and wearables (anything that is going to be next to your skin).  It washes up well too!

A lightweight chunky yarn, I felt it worked up similarly to Aran/Worsted weight.  If you’re substituting the yarn, crocheting your swatch will help you decide on yarn and hook size.  Having said that, gauge is not critical for this project but maintaining your tension is.

You only need 920yds/840m for this project which you might already have in your stash.

Pattern Notes

  • Chain 3 counts as a stitch
  • Chain 4 counts as a stitch
  • Rounds are joined with a slip stitch to the top of the turning chain and then slip stitch to the corner space
  • Section 1 classic granny square is worked in rounds
  • Section 2 corners are worked in decreasing rows.  After the first corner, rejoin yarn for each of the remaining 3 sides with wrong side facing in any chain 2 space
  • Section 3 first two rounds are to set up for the granny square.  Rejoin yarn on the right side in any corner. Don’t forget to work chain 1 before and after corner spaces. 
  • Section 3 first round – you will be working into the chain spaces as well as the corner spaces from section 2.  The image below shows the chain spaces and previous corner spaces. Checking each side stitch counts in round 1 will ensure you have equal sides.
