Knit Pro Blockers
Having these were a game changer for me when it came to blocking. If you've ever blocked a large shawl or a blanket then you'll understand.
You get 20 blockers (12 large with 8 pins and 8 smaller with 4 pins).
They're incredibly easy to use and way less fiddly than T-Pins (although T-Pins still have their place).
There are anchor hole in each block so you can attach a string along large sections which can be pulled and pinned to maintain a consistent tension.
Available in both a white and a multicoloured set.
Made with tough plastic with embedded sharp, study and rust resistant stainless steel pins.
