New knitter need help

Okay I am very new to knitting and I have just made washclothes to practice my knit and purl stitch. I was wondering if someone could help me with this pattern to make sure I am reading it right

"Cast on 140 stitches.

Row. 1 -10. knit.

[U]Row. 11 thru 20. - K 10 K 10, P 10 repeat to until 10 stitches left and K 10.[/U]
Rows; 21.-30. K 10 P 10, K 10 repeat * to * until 10 stitches left and K 10.

Knit until approx. 35 inches or looks good then Knit last 10 rows. "

Okay the underlined part of the pattern do I knit 10 and then knit 10 again and purl 10 and then repeat knit 10 purl 10 until 10 stitches left? Just want to make sure I understand
Webpage got the pattern from :

Yes, everything between the ** is to be repeated. Don’t repeat the initial k10, it’s the border, as is the final k10.

Yes, ma’am! Knit 10, then knit 10 more.

What is going to happen is that the first 10 stitches and the last 10 stitches will form a garter stitch border around the edge of your wash cloth. Then the inside will have a kind of checkerboard effect of Purl and Garter squares.

Hopefully that helps! Just remember that the first and the last bits are always knitted and form a border!

when it says #7 needles does that mean size 7 (US)?
Also what is sports yarn? the patterns says to use 15oz of it, how many balls is that?
Sorry if i’m being dumb, i’m new to knitting too.

[FONT=Comic Sans MS][SIZE=3][COLOR=#9932cc]As for how many balls, it will depend on the yarn you buy. On the yarn wrapper it will say how many ounces are in the skein, ball, or hank. If it only gives the weight in grams, you can find conversion tables on line. Or you can use a postal or food scale to weight your yarn to see how many ounces you have. [/COLOR][/SIZE][/FONT]

so if a ball of yarn was 5oz, then i’d need 3 balls?
ok i think I get it now. now just the daunting task of picking the yarn, i’ve no idea between all the different kinds. I guess it all just comes with experience :slight_smile:
