Hi Angela!  You can absolutely use a size 5 weight yarn for this blanket!  Just know that Temperature Blankets are yarn eaters as we are making 365 rows.  I estimate the blanket made with a size 3 weight yarn will be approximately 7 feet long.  So I made the width of the blanket 5 feet wide.  Using a thicker yarn means your blanket proportions will be bigger.  Your blanket might be closer to 9 feet long so maybe aim for a 6 to 7 foot width.  (Hint/Tip:  Temperature Blankets are not your normal throw blanket, they are commonly excessively long.  Think of this project more as a keepsake as you are recording history which makes this blanket extremely memorable and special).  Starting in January, just focus on that multiple stitch count requirement of Multiple of 2 + 1.  Use your measuring tape, and then check your measurement after 3 - 4 rows to make sure the width measurement has stayed the same or if you need to go back and adjust.  I hope this helps!  I'm so excited for you to join in!

Oh your blanket looks fantastic Fran A Fran! I love the colors and how they work together.  It's so pretty!  Thank you for sharing!

I'm thrilled you liked it! 🤗🧶💖

That's awesome Ria!  Feel free to ship however many at one time.  Even if it's just a couple.  Also, whatever might be the cheaper way to go.  WAY TO GO!  🤗🧶💖

That's a great idea Amelia! 

OH MY GOODNESS I LOVE YOUR PICTURE!!!!  Thank you so much for putting all of your red and pink colors together and taking this!  I think it's fantastic!  That is a lot of red and pink!  Is this one of your favorite go-to colors?  Or were you surprised to see you had so much?  😄🧶💖

Honestly, it looks like you spent maybe 5 hours on it.  So, when you said it only took you 3 I was very impressed.  Great job Amelia L. Amelia!

WOW Maria!  So many temperature changes but I LOVE it because your colors are absolutely stunning next to each other.  Seriously LOVE all of the colors and the muted, farmhouse kind of vibe they give off.  Your blanket it going to be so beautiful! 😍
