In Filet Crochet P2 I'm going to teach you how to increase and decrease. It can seem confusing at first, but is actually pretty easy when you get the basics down pat.
There is one new stitch to learn. Some instruction calls it a Double Triple crochet. I've also seen it called a Triple Triple (or Triple Treble) crochet. I'm going to go with Double Triple as I think its the most used in 'American' patterns.
Filet Crochet P2: Increase 1 Block at the Beginning of a Row
Chain 8 and Double Crochet into the first post. The 8 links of the chain represent 3 on the bottom, 2 up the outside, and 3 on the top. Your double crochet makes the left post closing the new block.
Increasing one block at the end of the row.
This is where the Double Triple Crochet (or triple triple, or triple treble) comes in. Start by chaining 2 stitches (makes the top of the new block). You can't see them in this picture because I'm pulling it tight for the photograph.
Then yarn over 4 times.
You will place your hook in the same place that your last post was made.
Draw one loop through the stitch AND through the first loop on your hook. Complete the process with 4 - Yarn over, draw a loop through 2 loops on your hook.
That makes the Double Triple crochet stitch into the box at the end of the row.
Filet Crochet P2: Increasing MORE than 1 Block at the Beginning of a Row
This is where your knowledge of the basics comes in. Just like in the beginning you will need to chain 3 for each additional block (minus 1 block), plus chain 8 for the last block you want in the new row. Example: If you want to add 2 blocks you would chain 3 for the first one, and 8 for the last one. Total of 11 stitches. If you want to add 3 blocks you would chain 3 for each of the first two (6), plus 8 for the last block. Total of 14.
Increasing 3 blocks would be chain 14.
The first Double Crochet would be in the 8th chain from the hook.
Chain 2, the next Double Crochet would skip 2 chains below and Double Crochet into the 3rd.
Chain 2, at the end of the increase your double crochet would be into the stitch above the post.
Increasing MORE than 1 Block at the End of a Row is using a series of Double Triple crochet stitches (or triple triple, or triple treble - depending on what you are calling it). The trick is where to put the stitch in the previous block.
As you look at your previous block you will see 3 groups of 2 threads. You want to place the Double Triple stitch in the center group (or in other words, in the second group below the top of the stitch). The picture below shows you where.
Continue with your Double Triple crochet stitches until you've increased to your desired blocks.
Filet Crochet P2: Decreasing Blocks at the Beginning of a Row, Chain 1 and turn, slip stitch across the number of blocks you wish to decrease. Pick up the chains between the blocks. End on the right side post above the block you wish to start on. Chain 5 and continue as normal Filet Crochet.
Decreasing Blocks at the End of a Row is the easiest of all. Just stop crocheting.
There is a bit of a trick to doing this, but it really is pretty easy.
Increasing 1 Block at the Beginning of a Row.
When you get the point where the next row adds 1 solid block, chain 5.
(You will be working in the two chains closest to the previous block post.) Start in the 4th chain from the hook and do 1 double crochet, followed by a second double crochet, and one more on top of the previous block post.
Here you see the new solid block added.
Increasing 1 Block at the End of a Row.
Picking up the "side" stitch of your last post, closest to the bottom of the stitch, triple crochet 1 stitch. You are actually working from the bottom up. Repeat doing the triple crochet stitches 2 more times.
Note that the bottom stitches you pick up actually look like a chain. Here you see 1 blocked added to both sides.
Increasing MORE than 1 Block at the Beginning of a Row.
The formula is 5 chains for the first block, PLUS 3 chains for each additional block. You start with a double crochet in the 4th chain from the hook, and in each chain there after until you reach the post.
Here you see 2 solid blocks at the beginning of the row.
Increasing MORE than 1 Block at the End of a Row.
Here you see a clear picture of the bottom, and the stitch you pick up for each added triple crochet. Add 3 triple crochet stitches for each block.
This is what the work would look like with 2 solid blocks added to each side.
