First things first, this pattern, when worked up, is gorgeous. Because it's an interlocking mesh, the weight of the blanket is double what it looks like its going to be and it ends up quite a hefty blanket for how big it is. But the pattern is deceptively difficult. 1. The pattern works up easier if you think of the two colours as separate entities almost. The colour A (white in my case) is a mesh worked on the SAME SIDE the entire time. The white doesn't weave!! The colour B (blue here) goes over and back the white stitches, but the white stays on the same side the entire time (see pic 1 and 2). If you make a mistake in B, you can frog rows and rows of B with no change in A at all, you just end up with a standalone mesh. If you make a mistake in A, you have to frog both rows, because the B is weaved in between A. And annoyingly enough, it's fairly difficult to see mistakes until you're working the next row OF THE SAME COLOUR, so potentially three rows have to be pulled out for one mistake. 2. I genuinely do not know how the edges between rows worked, to me, the pattern made no sense in this regard. Tried out multiple swatches, and never got it to sit right. To remedy this, rather than trying to interlock the two colours, I left the turning chain basically alone, then when the entire blanket was finished, did a border of doubles (UK) all around the edges. You cant see the empty chains or any difference now so I'd recommend that if you cant get the edges right. 3. It's a repetitive pattern, obviously, and I think that if I wasn't changing my B colours every so often I possibly would have gotten bored. It's also somewhat frustrating, because for every two rows of stitches you're only increasing the size of the blanket basically by one row. Again, if I hadn't been changing colours and didnt have a specific reason to be keeping an eye on my row count, I feel like it might have been disheartening to see the amount of work you were putting in versus the amount of blanket you were getting out. I'd recommend this pattern to anyone who has the patience for it, it technically isn't a difficult stitch, it's not a complicated concept, and I've certainly seen more elaborate mosaic patterns before. However, I'd also recommend anyone who wants to try this pattern to do swatches first. I think it took me maybe five swatches to actually nail down the correct interlocking forward/back of the colours that the reversible element of this requires. My finished blanket, (Pics 3&4), is approx. 32 inches wide (with 154 foundation chain), and approx. 60 inches long. Each colour block had 22 rows, so technically, the blanket was 132 rows of colour A and colour B long, but obviously I had to do 264 actual rows altogether. Again, this is a heavy blanket. I used a smaller hook than recommended for my wool (4.5mm instead of a 5.5/6mm) which resulted in a tighter mesh, with minimal gapping between stitches/rows.
