We present Craftec, an extendable toolkit system to engage older adults in maker technology by supporting their use of crafting skills. Craftec is comprised of LilyPad Arduino-based toolkits to promote easier crafting with hard and soft mediums. We describe the system's design, a pilot test with 8 younger adults, and 2 two-hour single session workshop evaluations by 17 older adults. We found Craftec facilitated efficient integration of circuits in crafted items, including fewer short circuits as compared to a basic LilyPad Arduino kit. We discuss how to create a toolkit for prototyping rather than facilitating STEM education.
