How to connect crochet squares comes down to two main approaches: joining as you go, working a connecting round directly between squares, or sewing them together after all squares are finished. I switch between the two depending on how much flexibility I want in my final layout. This guide compares them.
Join as You Go vs. Sew Together After
Joining as you go works a single connecting round of single crochet or slip stitch directly linking each new square to its neighbors as you finish it, avoiding a separate joining step later. Sewing together after gives more flexibility to rearrange your layout before committing, at the cost of an extra finishing step with a yarn needle.
Frequently asked questions
Which method is faster for a large blanket?
Join as you go is generally faster overall since it avoids a separate sewing session at the end, though it requires committing to your layout before finishing each square.
