Knitting with double pointed needles?
I am new to knitting and I'm trying my first project with DPN. I have the first row done (24 sts, 8 on each needle, 2K 2P for ribbing), but now I don't know if I should continue going in a circle, working the next sts on the very first sts, or should I turn and work back over my most recent sts first the way I would with flat knitting?
Thank you!
The nice thing about knitting in the round, and, yes, you will go around, not back and forth, is that outside of ribbing or stitch patterning, you never have to purl, just knit all the stitches, all the way around, every round. After while, usually a very short while, it becomes automatic and you find yourself knitting more quickly than before.

Double Point

Does single covalent bonds have higher melting point than double covalent bonds? Why?
Talking about Hydrocarbons here.
Which has a higher melting point(which melts faster)? The compund with a single covalent bound or the one with a double covalent bond? Why is it like that?
I need this urgently for school research. Thanks.
Bonjette is confusing melting and boiling points with molecular stability. Double bonds are harder to break, but melting does not usually involve breaking covalent bonds.
For 2 molecules with the same number of carbon atoms, and the same structure, the one with double bonds will melt lower.
There are two reasons I know of.
Firstly:
Each double bonded pair of carbons has only 4 groups bonded to it, while single bonded pairs of carbons can accomodate 6 groups. So double bonds lower the molecular mass.
Secondly:
The 4 groups bonded to a pair of double-bonded carbons are arrayed in a planar fashion, while the 6 groups bonded to a pair of single-bonded carbons are arrayed in 3 dimensions.
So, molecules with double bonds are less tangled and melt lower.
This same principle applys to boiling points.
