Hello and welcome to the forum
Yes, florist resin is dear, even if you get it by the gallon(showing my age there
)
It is quite tricky getting it just right, but worth persevering with.
Your vases have to be squeeky clean as any dust or marks in the glass are there for everyone to see, forever.
It takes ages to set so you have to have your display held in place or everything just flops to one side without support.
Thats why they are expensive to buy, cost of materials and all the pratting about.
When you have done about 50 you will get the knack
Put a piccie up when you have done them, we like to see each others work.
Good luck
