One of my boys' favorite gifts we gave them last year, was the gift of an indoor snowball fight. We live in an area that doesn't really get any snow, so that made is even more special, but I think all kids would like this gift. This could also make a good rainy day activity for January.
I wrapped up mittens and "snowballs" for each of my two older sons and labeled them indoor snowball fight. We had them open the gifts at the same time, and then off they ran chasing each other and throwing their soft fleece balls.
The quickest, easiest way to make this gift would be to pick up some mittens or gloves and white socks (roll them up in balls) for each child. If you want to hand make this gift there are lots of great mitten patterns for free or sale on the internet. Or you can even just trace around the child's hand with enough margin for seam allowance.
You can quickly sew up soft fleece balls by cutting 4 ovals the same size. You want elongated ovals, not to round or you will end up with funny pumpkin shaped snowballs like some of mine were. Although in the end my kids did really like that, because they could stack them up and build "snowmen: as well (like in the top picture), so it is your call. Sew them together right sides together halfway around the oval top to bottom (the long side of the oval). Continue sewing ovals together until you have all four sewn together with only a small opening to turn and stuff. After you turn and stuff the fleece ball whip stitch or invisible stitch it closed, very securely since these are going to be thrown all over.
Either way kids will have a great time with this simple gift and get useful mittens (and perhaps socks) out of it as well. It might just be the most fun way to package mittens and socks for gift giving. :)
I think this would be a great gift if you needed to give something to all of the children in the extended family, unless the gift exchange takes place at Grandma's house in the living room full of crystal. Only Grandpa can bounce a tennis ball off the wall in that room and not get yelled at.
