Stash-busting Blanket Information
I wanted this CAL to be relaxing and friendly and be a real Stash Buster. You will need a few balls (approx. 1000m) of your main colour for joining and border. You have creative freedom to choose your own colours, and I want to encourage you to do so, and have fun!

Notes
- As such, gauge is not critical in this project. What is important is that all your squares are the same size.
- My blanket is made using DK weight yarn and 4.5 mm hook and each square is 6.5in. If your tension is very loose you could use a 4mm hook
- It’s generally best to stick to the same yarn brand if possible, to avoid drastic changes in the yarn’s thickness (which can affect the size of your squares)
- You could use worsted weight (aran weight) if that is what you have. Your finished squares will be approx 8in
- The squares are designed to be all the same size after blocking. Your stitch count for final round of every square ,will be 24 dc (tr) each side of square
- Blocking will even out any minor differences in size. I pin them to my ironing board to the same size template each time, and steam them. After they cool down they will be a beautiful polished square!
- Use the same hook size throughout the CAL and block your squares to keep the size consistent.
- Check your stitch count at the end of each round to make sure you are on track.
- I suggest you use the Invisible Joining method to finish rounds of the Solid Square, and all rounds of the Primula Square, for a neat consistent finish. I have provided Instructions on how to do an Invisible join in this post.
Photo Tutorial for the Invisible Needle Join

You will need the pattern for the Solid Square this week as well as the Primula Square. The solid squares are included in between the flower squares in the blanket.
Some of the flowers squares are open and lacy so the solid ones give weight to the finished piece. You can make them in different colours as I did, or in a single colour if you prefer……have fun designing your own unique blanket!
