Well ladies, let me tell you my experience with both products.
HATE sugarveil but absolutely LOVE cake lace --- unfortunately I'm in the USA and cake lace is in the UK and yup I paid a fortune on shipping!!
Sugarveil was total nightmare for me -- the first time I made it it never set...the next time I tried drying it in my oven under the oven light, and this time it got so dry that it broke in a thousand pieces -- So, the third time it, sort of, worked but it was a struggle to apply to the cake and when we cut it I noticed the lace dragged which looked awful...it was a cake for my daughter so I helped to cut it.
I honestly don't know if I got a damaged product or it was too humid in my house or what happened but it did NOT work for me. That was about a year ago and I don't know if their product has improved by now, but I have not used it again...and I still have a big bag of it sitting in my cover
Now, let me tell you about Cake Lace... it is HEAVEN in my world --- it worked perfect the first time!! It set faster than I expected and it stayed flexible, soft but it did not break easily. I also experimented by freezing (already made lace) for about a month and guess what? it defrosted perfect and was still flexible and soft!! I totally love it and I don't care if I have to pay a fortune for something that work as well. Oh, and it does not drag when you cut the cake. So, there you have it.
Btw, my whole life I've loved lace and when I discoved cake lace I thought...."Ahhh, this was made exclusively for me" lol
Sorry for the long post, but I had to tell you my experience. Maybe sugarveil has worked for some of you, but it didn't for me.
