The Building Blocks Collection (consisting of the Hat and Blanket) is available as an ebook here for £12 + any applicable local tax.
Released in March 2021, The Building Blocks Full Set (consisting of the Hat, Scarf and Blanket) is available as an ebook here for £17 + any applicable local tax.
If you have previously purchased the Building Blocks Collection and would like to add the scarf to your library, add the scarf as an individual pattern to your cart and a discount will be automatically applied so that your total spend will be equivalent to purchasing the Full Set in the first place.
I also have a pattern (not include in these ebooks) for the Building Blocks Washcloth which is a good introduction to the patterns in this collection if it is your first venture into colourwork/Intarsia.
