How to make Sheldon the Turtle twice as big...?
If I want to make a pattern twice as big (for example the sheldon turtle pattern from knitty.com http://knitty.com/ISSUEwinter06/PATTsheldon.html ) do I just double each rows' instructions?

For example:

Pattern as orginally stated on knitty:

Using MC and straight needles, CO 12 sts.
Rows 1-2: K all sts.
Row 3 [RS]: Join CC. Kfb, sl 2, k6, sl 2, k1. 13 sts.

Would this be correct to double?:

Using MC and straight needles, CO 24 sts.
Rows 1-4: K all sts.
Row 5 [RS]: Join CC. Kfb [twice] , sl 4, k12, sl 4, k2. 26 sts.

If this is not correct can someone please show me what would be? Thanks!

WHAT a cute pattern!
I was determined to design a turtle myself. Just all on my own. But now I need to make Sheldon. I bookmarked the page! So CUTE!

Looking at your enlargements.. the kfb twice can not work out. you look at the turtle and you see those lines forming. Those happen because of increace and decrease in the right places.
I would just do kfb and then you have twice as many rows so you just repeat that in the next row up.

It will surely change his shape making him bigger that way. you may or may not like it.
I would say: Thicker yarn, thicker needles, and that is the safe way to make it bigger. Adding and multiplying is almost as tricky as designing, well, not quite... but write it out carefully and think it trough once before you end up with frustrated pulling out!

It would probably be a lot easier to just use heavier yarn and larger needles. A size 6 and 7 maybe. Then just follow the pattern as written.

I was wondering about needle sizes if I chose to go that route, the orginal pattern says needles size 3 and 4. Size 3 is 3.25mm, so doubling that would be 6.5mm or size 10.5 US.

Why do you suggest 6 or 7? And how heavy yarn should I go?

I'm wantong to double this pattern so that I can fit it to a newborn back for, cute naked turtle baby pictures!

...On the otherhand I am a little narsistic and a perfectionist, and now I'm dying of curiosity to know why doubling the intructions isn't advisable.

the pattern starts with 12 stitches, then increases.
If you start with 24, there is a lot longer of a straight edge as you would have before. So the shape would look odd. occasions like this one will happen in several odd places of the shell.

It is like legos. when you build something out of legos it can look pretty neat. Build the same thing out of the bigger toddler blocks and you will see all the edges.

In knitting some things just work perfectly in one way and will not if doubled.

the idea with the newborn is kind of cute but I don't think you can easily fit one in the shell. a baby is not as stuffy as this turtle.
you will need a LOT of space for the head and more room for the legs than the turtle gives...
maybe do not join the pieces (maybe use snaps or velcour)? or make the belly piece even wider, but knitt ribbing from side to side to that it stretches?

No no. It really doesn't work that way. If you just double the instructions you'll end up with a really short and really fat turtle. You have to increase the number of rows that you do along with the increasing the pattern significantly otherwise it just distorts the proportions. You have to create a swatch and determine the number of rows you get per inch and then calculate the height and increase the number of rows by the proportion you get. Its really a pain.

I would go along with suzeeq. Just increase the yarn and needle size. You won't get double the size, buy you will at least get bigger.

trvvn is right: stitches are not normally square. they ususally are not aswide as high or the other way around.
Easy: the width is detemined mostly by the yarn that sits next to each other leaving some gap. that is how wide the stitch is.
how high it is depends mostly on the diameter of your needle. bigger needle means more slack, means more hanging of the stitch, therefore higher stitch.
bigger needles DO add a little width, too. but more hight. That is gravity's fault.

How about you use double string? 2 coils of the same knit simultaneously? bigger stitches, more material, need for a bigger needle.

just careful: you want to stuff the shell. if the needles are too out of proportion for the yarn there is too lose fabric. you will see the stuffing through!

I get what you are saying, as for the baby, Im not planning on making the bottom, I was just going to make the top shell and stuff it, then make to 'backpack' straps. Thanks!

Just before I came back to the forum to see if I got any more insight I decided to just cast on my theory for a few rows, and came to the exact same conclusion as I was pulling it all out and came upon your post at the same time! lol I couldn't visualize it on paper, but once I started I immediatly realized that I wasn't doubling the length on every row either.
