Confused

so I am making a dog sweater and having trouble understanding what to do or what it is asking me. also i do not have a double sided needle. is there any way i can continue this without it? here is what it is saying…

“Next Row (Right Side): K5 (5, 7, 11, 13), join second ball of yarn and bind off next 4 (6, 6, 10, 13) sts, work to last 9 (11, 13, 21, 26) sts, join third ball of yarn and bind off 4 (6, 6, 10, 13) sts, knit to end of row.
Working all sections at same time with separate balls of yarn, continue in St st until pieces measure 1 (11⁄2, 11⁄2, 21⁄2, 3)” from beginning of Leg Openings, end with a wrong side row.”

any help?

You’re going to knit the sweater in 3 sections and do exactly what it says to make the leg openings. Each section has it’s own yarn (doesn’t have to be an entire ball you can take a strand from both ends of one). Knit the first sts, drop that yarn, pick up another end and BO sts, drop that yarn and pick up the 3rd end and BO those sts then knit to the end of the row. Then you drop the yarn when you come to the gaps and pick up the yarn on the other side of each of them. After knitting them separately (but at the same time, as if they were all on one row) for a couple inches, you join them again on one row using just one strand of yarn.

i only have one ball of yarn i can use both ends but it calls for 3 balls. also i do not have a double sided needle. and do i use 3 different needles or the ones I’m putting aside to i put on a holder? this is a little confusing

You can work each section separately, just make sure you end them all on the same (RS or WS) row so you can knit a row that joins them together. You should be able to work them across a straight needle. After you BO the leg openings you’ll have less sts on the needle and can just shove the sts from the one you’re not working on toward the back of the needle. You could also cut off a long length to use for one of the sections and use both ends of your ball for the other two, but it would be tricky to get the right amount.

After you BO the openings, you’ll end up with a piece that looks a little like this -

While your directions call for you to work all sections at the same time, you could actually do them one at a time. It’s a bit trickier to get them all the same that way, I don’t see why you need double pointed needles (dpn) for this. As you work along, it will all make more sense to you. All the advice above should help it go smoothly.
