How Much Resin to Buy for Holiday Gifts

Short answer: add up every piece you plan to make, add 10–15% for waste and test pours, then buy the kit whose combined A+B volume covers it. As a guide, a 4 in × ¼ in coaster takes about 51 ml and a 3 in flat ornament about 29 ml (geometry: 1 in³ = 16.387 ml). Enter your gift list below.
