Spring Fever and Piping Practice

Unseasonably warm temperatures have me thinking about spring flowers. 
Yes, spring fever has struck and I succombed to it by making floral cupcakes for the Ladies Tea and Luncheon at church. Spring fever isn't the only reason I made these cupcakes. 

I have been wanting to practice piping buttercream flowers with my new petal tips. 
I did find that piping the flowers individually on a flower nail was time consuming. However, I believe that the end results were worth the amount of time spent piping each purple bloom onto a square of parchment paper on top of a flower nail. What do you think? 
I also piped the daisy/aster blooms indiviually. 

Purple flowers - 104 tip and a 3 tip for the yellow centers
White flowers - 102 tip and a 5 tip for the centers
Green ruffles on the cupcakes - 104 tip
Yellow drop flowers - 224 tip

The Cupcakes
Lemon and strawberry are the two flavors I chose to use in these cupcakes. I purchased a box of each flavor at the local grocery store. After mixing the cake batters, I put about 2 Tbsp. of yellow lemon cake batter in each cupcake liner. Next, I topped the lemon cake batter with pink, strawberry cake batter. A swirled "S" with a butter knife created marbled cupcakes that are pink and yellow. 

I made 2 dozen cupcakes and used the left over batter to make 1-9 inch layer cake. After cooling the layer cake, I wrapped it in plastic wrap and it is in the refrigerator freezer compartment waiting for me to torte it, or slice it crosswise, and to fill/frost with buttercream frosting.
