It is difficult to say if I've ever had a favorite pattern, but here are two that I have completed most recently.
The purple afghan pictured below is called Sweet Dreams and came from a Best of Terry Kimbrough Baby Afghansbook. The book is complete with 24 patterns and beautiful pictures of each cozy wrap. I love how the afghan turned out in the purple - and it's perfect for those little ones that love to push their tiny fingers through blankets.
The next one is a free pattern from Posie Gets Cozy. The Tiramisu Baby Blanket is as delicious as it sounds. This was the first time that I used 100% cotton yarn and I think it is gorgeous. Of course the ribbon weaved through the edge of the blanket ties it all together. Thank you Posie Gets Cozy - I did enjoy!
Perhaps you have favorite pattern you would like to share. I always love a new idea or project that I hope to get to one day. Or if you don't crochet, I would still love to hear what one of your favorite things to do is.
