Scrap afghan question--uneven edges?

[Reba]

I have a quick question about a scrap afghan I'm planning; I wanted to ask it before I get started, so I don't have to frog a bunch of my work.

 

I'm planning a scrap afghan, using the remains of different yarns I have lying around. I really like the idea of using yarns of different textures and weights, but how do I address the changing gauge issue? If I use the same number of stitches in every row (regardless of what type of yarn I'm using), won't the edges come out uneven? Will I have to eyeball it? Should I just work three or so strands of regular yarn together? I'm planning on doing a really simple pattern, maybe just SC the whole way (if you have any suggestions about that, I'll love you forever).

 

Any help would be appreciated. Thanks!

I was going to say do the two or three strands together.

You might also do something like a shell that'll give you more stitchs in that row.

i do this and use the same size hook for every thing like a P even on the thinner yarns.. it turns out a little uneven but nothing a little blocking wont fix or a little folding under to hide LOL

I'm lazy and never block. lol

 

I'd also do some kind of boarder around it all. Something lacy maybe to fill in it in, nothing solid as that would show it up I think.

I'm a new crocheter, so I have no idea how to block LOL! A border is a good idea, though--maybe something kind of ruffly.

 

I do have one more question, though. I don't want each row of the afghan to be just one color, I want to be able to change colors mid-row to make the afghan really funkydelic. How do I change the yarns, though? Should I just knot them together, or will it be secure enough if I just work each new yarn in?
