The flat braid join method is a very pretty, lacy method for joining squares. It is very generous when it comes to joining squares that do not match up exactly in stitch count, just adjust the number of stitches that are skipped for the chain 3 sections so that you have the same number of loops on each side.
To join squares using the flat braid join method:
Written in US terms.
1 – attach your yarn in the corner of your square with a single crochet, chain 4, single crochet again into the corner space – this creates your corner loop
2 – chain 3, single crochet into the next space. Repeat this across the entire side of the square ending with a single crochet in the corner space. ** for your first square you will repeat this around the entire square – single crochet, chain 4, single crochet again in the corner spaces, chain 3 for the sides of the square) **
3 – chain 2, remove your hook from the loop, insert it through the corner loop of the square you are joining to, re-insert hook into the chain loop, pull the loop of the chain 2 through the corner loop, chain 2, single crochet back into the corner space of the square you are joining
4 – chain 2, remove hook from chain loop, insert hook through the next loop on the square you are joining to, re-insert hook into the chain loop, pull chain loop through the chain 3 space of the square you are joining to, chain 1, single crochet into the next space on the square you are joining. Continue this down the side of the square. ** if there is only one square to be joined to at this time, continue to #5, if there is another square to be joined to along the next side, repeat #4 to join that side as well **
- When you move to a second join side -be sure to move into the first chain 3 section on the side of the next square rather than the corner section of that square or the sides will not line up properly! You should end up with a small honeycomb-like gap in between where 4 corners meet.
5 – continue to chain 3, single crochet into the next space and chain 4 in the corner spaces around your square. Join with a slip stitch when you have completed your square.
