Crocheting Easter eggs is one alternative to both plastic and real eggs. You could even decorate the eggs with buttons, stickers, etc. This is a great little project for leftover yarn.
I didn’t create a pattern while working this up, but basically start with a base of 6 single crochets in a round either by starting with two chains and working six single crochets into the first chain or by starting with a magic ring and placing six single crochets into it. For the next round, increase twice into the first and third single crochet. The rest of the single crochets just place one single crochet. You should have eight single crochets in the round.
Continue to increase this way until you have the desired size of your egg. Then do three rows of even single crochet – that is each single crochet will just have one single crochet in it.
Then you can decrease the rounds much like the increase with two decrease stitches each round. Stuff before closing the egg.
The best thing about these crochet Easter eggs is that after Easter you can always frog them if you no longer want them. These crochet eggs make a great fast, easy, last minute craft for Easter.
