You can use your hands and do the chain stitch over the first chain stitch. Ussaly people do this to make sonething thick. Like a potholder.
Work one double crochet in the chain after the one you've just used. Then work another double crochet into the SAME chain where you worked that first double crochet.
In crochet, because stitches have "height" (where in knitting stitch height isn't much of an issue), crocheters add chain stitches to the end of a row to add height, in order to begin the next row.So, in your instructions, chain 4, then make a single turning chain, would mean to add another chain, turn your work so that you could then begin crocheting the second row. You would then insert your hook into the second chain from the hook and crochet the next stitch (which is going to be a single crochet--sc--due to only using one turning chain)There is a standard turning chain number, depending on the stitch you are going to use in the next row. [the link shows how many turning chains for each crochet stitch].For a:slip stitch = 0 turning chainsingle crochet = 1 turning chainhalf double crochet = 2 turning chainsdouble crochet = 3 turning chainstriple crochet = 4 turning chainsand so on.You see that as the stitch height grows, so do the number of chain stitches in your turning chain.
Most usually you start in the second chain if you are working sc, the third chain if you are doing dc, etc. The pattern usually says where to start.
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.
The single crochet, double crochet, half double crochet, chain, slip knot. They can all be explained at the related link below, which has tutorials.
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.
To make 88 single crochets, you would make 89 chain stitches and go into the second chain from hook to make your first single crochet. To make 88 double crochets, you would make 90 chain stitches and go into the 4th chain from hook. The first 3 skipped chains count as a stitch which is why you are ending up with only 2 less than the original chain.
Sp in crochet patterns means "space" as far as I know. Generally, a space in crochet is created by the chain stitch(es) on the previous row/round. If your pattern states to sc, (single crochet) in the next sp (space) it means to pull the yarn around the stitch (the chain stitches) rather than through the chain stitch as you'd do when working into your beginning chain.
foundation chain
When you work into a crochet chain you insert the hook between the top two and the bottom one strand of the chain. When you get to the end of the chain you can carry on round and work more stitches into the remaining one strand of the chains.
It means "single crochet". The stitch is the shortest of the crochet stitches and makes a very compact garment. Other notations can be double crochet, half double crochet, and even double triple crochet.Always read the whole pattern thoroughly before you begin your work.To sc in sc means to place your next single crochet stitch into the next single crochet stitch from the previous row. If your next stitch is a chain, for example, you would skip it and go to the next single crochet. Be aware that sometimes there will be a typographical error in a pattern, so be alert to how the stitch works in the pattern you are using.
