I have a fantasy each Christmas of my children taking time to carefully consider each other's likes and craft sweet, thoughtful presents for one another.
This has unfortunately never quite played itself out well. Probably because I have been a smidge too hands-off in my role as adult over-seer. For instance, last Christmas my then-7 year old made a personalized sash (yes, that's what it is. see above photo) for her 4 year old sister. I'm so sorry to say that it was not received with delight.
This year, I'm going to try ONE MORE TIME to salvage this fantasy but I'm taking the bull by the horns: each child will choose something they can make in a batch for their siblings and that thing will be a cool thing they can choose off of a list of projects that I will assemble.
My ideas so far have mostly come from careful perusal of Design Mom's trove of DIY sibling christmas projects. I'm thinking especially of the bleach shirts, pocket hand-warmers, decoupage sketchbooks, and bubble bath. Also great could be jewelry boxes, jewelry, or frankly, cookies.
Ideas? Once more pinterest is a valuable tool for such research... I'd love to hear things that have worked well for you!
