Cut your string about 1,50-2 meters long.

Add one seed bead on string.

Add 2 more seed beads. Criss-cross string trough 2 last added beads. Make them more tight to the first bead. Next step is the same. Repeat this step 3 times. If you want your croc's belly different colour as back,then do like this:

1.step-back colour beads
2.step-belly colour beads
3,4,5,etc.step continues like that.

So actually this step goes 6 times.

Picture for understanding last part of step 2.

After 6 steps,here you are!
Add 3 seed beads on string.You know what you do with them,right?
Repeat this step 4 times like last steps.

Easier for me,i will tell you how much beads you add on next steps and also how much times these steps repeats:

after last steps-

add 4 beads,repeat 2 times;
5 beads,2x (then you add legs here,tell you after all of this);
5 beads,2x;
6 beads,8x;
5 beads,2x;
4 beads,2x;
3 beads,2x + legs;
4 beads,2x;
5 beads,2x;
5 beads,2x + eyes;
4 beads,2x;
3 beads,2x;
2 beads,2x;
1 bead,1x.

About the legs!

I hope you understand something from my picture. So,when you're done with first 5 beads (and also later when you are done with first 3 beads),add 4 back and 3 belly coloured beads at one string on the side.Don't criss-cross beads with the other one side of string!
Where was i...oh,when you add beads,then criss cross first 4 beads(back coloured)with the same string you used to add beads on for this leg.Thats easy-you should understand that. :)

Continue on you beading.

If you don't want your croc blind then add two eyes to it,right?

So,do you remember when i said 5 beads,2x + eyes before? At this step you add eyes to your croc.But only for one step! You dont want your croc 4 eyes-2 like usual and 2 more on belly side,do you? Then do like this:

1.step-add eyes(1normal bead,1 eye,1norm.,1eye,1norm.)
2.step-all 5 beads belly coloured.
After this,continue on beading!

After you're done,tie both sides of string and you are really done with your work.;)

Look at this picture and photo at the beggining(with all of my greatest crocs).If something's wrong,then its not my fault because i tried to explain everything as clear as can(it was really hard to me!).

But hey-make someone happy with these crocodiles!It's a perfect gift,i can say.;)
