If you are already familiar with the virus afghan with 4 sides than you will be ready to go. If not, no worries, you just may need to flip flop between this pattern and the original found here http://www.ravelry.com/patterns/library/virus-blanket
I created this 5 sided design myself. No pattern guidance other than the traditional 4 sided as noted previously. I am using 2 skeins of red heart yarn, one solid and one variegated and my favorite 5mm H8 crochet hook. This pattern can work up to whatever size you choose. Please enjoy and if I have an error in my instructions let me know. Thanks!
