9 or 10 degree ruler
 

I could only purchase 10 degree ruler. Followed all the instructions for this spicy spiral .it seems to work as well. This is a 80 birthday present for a quilting friend who has not seen this pattern.

Your friend should love it. Beautiful job! I have admired these for a while and did not realize that you needed a special ruler.

Great gift your friend will love it.

I would love to receive that as a gift. Good job.

Beautiful. On my bucket list.

good colour combo

nicely done... thanks for letting us know about the substitution

love the black and whites, this is on my to do list

Looks great!

What length and width do you end up with when using the 10 degree ruler?

Looks great!

Beautiful gift!

40 by 21 inches.

It is beautiful. Love the colors and the hearts. Need to find that pattern. I didn't know it needed a special ruler; however it does make since. Your friend is going to love your gift to her and think of you every time she looks at it.

Great job , love the colors you chose too ! I have the ruler, but have been a little intimidated to do this one, but it's on my bucket list too.

You did a beautiful job - I have made one with the 10 degree ruler also - it works great.

Wonderful work!!!!!

omgoodness, what a beauty. love making these

Well I live under a rock. I've never seen such a fantastic quilt!

I have been having this pattern and ruler for quite some time but have been hesitant to start it. May have to rethink this pattern and give it a try. Yours is very pretty!

great spiral!!
