How do you block crochet squares matters specifically because blocking each square before joining produces a flatter, more uniform finished blanket than blocking the whole thing after assembly. Block every square individually before you start joining. This guide covers why and how.
Why Block Before Joining
Individual squares are easier to pin to exact matching measurements than an entire assembled blanket, ensuring every square ends up the same size before they are joined together. Blocking after joining can leave inconsistent squares that never quite line up evenly.
How to Block Each Square
Wet block cotton and acrylic squares by soaking, squeezing, and pinning to identical measurements on a blocking mat. Steam block wool squares the same way, holding an iron just above the pinned, dry fabric.
Frequently asked questions
Should I block squares before or after joining them?
Block each square individually before joining for the most uniform, flat result, since it is easier to pin one square to an exact measurement than an entire assembled blanket.
