This is easier explained in photographs or video.
The letters sc are found in crochet instructions and are the abbreviation for "single crochet". The instructions are telling you to make a single crochet stitch in the last stitch of the row you are working.
DC as written that way would only mean double crochet in crochet .. only thing I can think of it is a knit pattern and in the finishing they tell you to dc around meaning to double crochet around which does happen too or somewhere in the knit pattern they want you to double crochet .. last idea someone made a typo and they meant to say dec = decrease ..
I believe this would be: hold the last loop of each stitch on hook (which means to stop one short when doing your final pulling though for the stitch) skip next two single crochet (meaning to simply not do anything in those next two single crochet stitches and jump over them.) three triple crochet in next single crochet. (meaning to make three triple crochet stitches in the next single crochet after the ones you skipped.) I hope this will clear that up.
Now, I'm not the best at reading crochet directions, personally, I like symbol crochet charts to read. To me, it's easier to understand.Okay, my best guess would be that you:double crochet twice into a single chain stitch (from the row below)do it again (double crochet 2 stitches into the next chain stitch)now, skip the next chain stitch (don't stitch anything into that chain stitch)now, double crochet into the following chain stitch.Without punctuation is it unclear whether you are to repeat the above stitch set in the order given five times, or whether it means to repeat the last instruction (double crochet in next chain) 5 times. If you have a photo of the finished piece you should be able to tell if there are five double crochets in a row as the last part of the repeat.
Do a double crochet stitch in every chain stitch until you reach the end of the row. When you come up to the chain three that you did at the end of the previous row, look at where you chained 3 and then do a dc in the last chain stitch of your chain 3.
One beat.
The technique for crocheting a second row in a piece differs for each stitch. For example, for single crochets, you go up one chain, turn and go into the first loop on your piece (the top that looks like a braid or a v). For double crochet, you generally chain up 3 and go into the second stitch of the row. The number of chains needed may vary depending on the personal tension of the crocheter and how tall your stitches are. However, it is important to note that in single crochet, the chain up does NOT count as a stitch and in double and triple crochet it does. This makes a difference in which stitch is worked as your final stitch of the succeeding rows. If you miss the last stitch, or you go into the wrong first stitch, you will lose or add stitches on each row causing your work to go in directions you did not plan. You might like to check tutorials on Youtube which demonstrate the technique.
To do a double crochet do a yarn over, insert your hook into the next stitch, do a yarn over, pull the yarn through the stitch, yarn over, pull through 2 loops on the hook, yarn over, pull through the last two loops on the hook.
You do all of that in the same chain. Make a double crochet by wrapping the yarn over the hood and inserting it in the chain and pull the yarn through, wrap the yarn over the hook and pull it through two loops then wrap the yarn over the hook and pull it through the last two loops. Now chain one and do another double crochet but do it in the same chain instead of going to the next one.
The way I learned to join another yarn to my crochet project is to add the new yarn to the stitch you are doing, when there are two (2) loops of the stitch left on your hook.For example, I'm going to add new yarn to a double crochet project. So I would do my dc (double crochet) stitch by beginning with:yarn overinsert the hook into the next stitchyarn over hook againpull hook through stitchyarn over hook againnotice that you now have the last two loops on your hook, this is where you bring in your new yarn,grab new yarn with your hookpull through the last two loops remaining on your hookyou have now completed the dc stitchcontinue your project as written.
If I was crocheting with two strands of yarn and switching between the two, I would think about laying the unused strand over the top of the row below and just crochet my next stitch as usual. That is, if I were switching yarns in a single row. If I were switching yarns on different rows, I would just bring the unused yarn up on one side, by crocheting around it at the last stitch of the row. Personally, I've not tried it, but those would be my suggestions. Bringing a yarn "along" and crocheting it in the row below is done in Tapestry Crochet (best know patternmaker: Carol Ventura). There is a different "process" with Tapestry Crochet, as you don't turn your work, and you use single crochet (sc), only.
Shanghai refers to a check out using the treble, single and then double of the same number. It is mostly used for a 120 check out, treble 20, single 20 then double 20. The single and treble can be in any order, but the double must be the last dart.
