In this video tutorial, learn how to join corner to corner crochet squares using the mattress stitch for a clean, invisible seam! (This technique will also work well for granny squares or other crocheted blocks.)
As I mention in the video tutorial below, using the mattress stitch to join C2C squares will work the best if you've added a single or double crochet border around the squares. (Here's where you can learn how to add a border.) You need the regular crochet "v"s to work the mattress stitch into and the C2C squares on their own don't provide that.
I really like how the resulting seam lies really flat and is basically invisible. It almost looks as if the squares are fused together! Let's be clear though, the seams are nearly invisible, but that doesn't mean this C2C Christmas afghan is not without its flaws.
The backside of the afghan is a bit of a mess, the junctures where the squares were seamed were kind of warped (luckily steam blocking with an iron helped a lot!) and there are a few design details I might tweak if I could do it all over again. BUT, you know what? I'm pretty happy about how it's turning out for my first attempt at C2C crochet. I hope my family gets a lot of snuggles out of it this year.
Next week I'll be sharing one final optional corner to corner graph to finish off the afghan and then friends, this began-in-August-so-I-could-finish-it-early-but-now-am-working-on-it-in-December afghan will be a wrap!
