Excellent lace mat, gorgeous effect!

I love this lace mat and am considering getting another so I can do multiple tiers at once. This mat was large enough to cover the outside of my 8” cake with just one large sheet and the design is busy enough that blending the seams is super easy. I’m just a hobby baker and it was easy enough for me to use, you just need patience in getting the lace out! 10/10!

Very Sturdy Cake Dummy Round

This cake dummy round worked perfectly for the wedding cake that I made. It was easy to work with. It was sturdy and the price was good for what it cost. No one knew it was a fake cake. I would definitely buy again.

Beautiful

These are so beautiful. The pictures do not do them justice. They were also packaged so well that it would be impossible for them to break. Will definitely purchase again!

Unexpectedly larger than anticipated~

But I’m not unhappy! I adore Global Sugar Art’s products, and wasn’t even aware they made this size, so image my surprise when I expected a small 10” cake box and got these lovelies!! 🎂 I bake a LOT of 10” cakes, and this allows me to bake 10” double tiered cakes that I can safely take to their intended destination safe AND looking pretty! I’m one happy baker right now ✨🤍✨💙✨

Perfect

This icing was perfect for my grandsons 2nd birthday Cookie Monster cake! I was afraid there wasn’t going to be enough but when I added the butter and powder sugar (as per directions) it was more than enough and tasted even better! Used it in a piping bag (tip 233) and Cookie Monster came to life! Will definitely order again!
