This is also my first time making royal icing. It turns out that making the icing is so much easier than decorating with it. I used a no. 1 tip to make the outline, but it still produces thick lines. I think I put too much pressure while squeezing the pastry bag. I shall try better next time. :)
I love how the colors turned out. The pastel colors gave a subtle feeling to the cookies. As you may notice above, the green and orange hearts are glossy while the blue and pink hearts are matte. This is because the picture is taken before the orange and green icing dried.
