Key Lime Pie
Decorated with Russian Piping Tips -- love this new tool! Works really well with stiff whipped cream. http://cupofsugarpinchoflove.blogspot.com/2016/07/the-lovely-limes.html
Looks pretty! Never thought of using whipped cream.
Thank you @Sandi1234 ! The whipped cream worked really well and since the pie is kept cold, I didn't have any issues with the flowers losing shape (and it's so much easier to make than buttercream lol)
