Needle US#10 can be used to make blanket bigger, but you might need 4 skeins instead of 3. I used full 3 skeins. There was almost no yarn left. One skein makes almost 7 blocks.
Pattern can be increased by adding more blocks to the project. One block is 5.5”x5.5”. Blanket 4x5 blocks is about 24”x29”.

Enjoy!
