Free Crochet Octopus Pattern
If you have been looking for the easiest pattern to start off with, look no further than this octopus pattern, which has got to be one of my easiest pocket animals to follow along. Just simply make the start of a sphere and end off with some curly cues. There is a sewing option and a no sew option too! Check it out below by clicking on the image or the button.
Free Crochet Jellyfish Pattern
This easy crochet fellow can be worked up entirely in one colour, or in alternating colours. The pattern is very similar to the octopus above with slight variations, the tentacles face downwards rather than sideways. The whole animal is made entirely continuously and sure to work up really quickly! Make him into a jellyfish keychain or a jellyfish plush.
Free Crochet Dolphin Pattern
Here with some body shaping and adding popcorn stitches as the fins, you get a dolphin! Easy to work up with only minimal colour changes and no attachments at all, they make great quick gifts, for teachers day presents or as mini gifts to loved ones. If you love marine life, after trying this pattern, be sure to try the whale pattern next.
Free Whale Crochet Pattern
This is an easy extension from the dolphin pattern because the body structure is almost the same! These whales are basically the dolphin bodies flipped upside down! There are a few colour changes here and there but equally easy to whip up with no sewing involved, making use of the same popcorn stitches for the fins. Finish both the dolphin and whale for a nautical adventure!
Free Turtle Crochet Pattern
Here the pattern gets slightly more complicated because of the colour changes involved. The head, body, flippers and shell are made entirely continuously without sewing, which means there is a fair amount of colour changes. He is still very much quick to finish and no sew at all. Made with vibrant colours, he can turn out looking very different!
Free Penguin Crochet Pattern
The main body for this penguin is easy to made, mostly a cylinder shape but his wings get a little more complicated with taller stitches extending out from the main body. Finish this little guy to complete the whole sea adventure crew and change up the colours to make him more colourful! Go ahead to click on the image below or the button to see the free pattern.
