Budget Planning

The cost of large, deep silicone molds can vary. Consider the amount of resin required, as this will be a significant part of your overall project budget.

These molds are excellent for year-round crafting. However, consider purchasing them in advance of major holidays like New Year’s or for summer projects where preserving flowers from events like weddings or gardens might be a priority. Buying before peak gifting seasons ensures you have ample time to create personalized gifts.
