I also tried out the Stix2 wrapping seals that came with the Crafty Creatives Christmas box. These are adhesive discs to use instead of tape. They are really easy to use and having tried them on numerous shapes and sizes of presents I found they work best on small to medium sized parcels and ones which are square and firm as you need to press them on to ensure they give a firm seal. On larger presents and odd shaped ones I went back to using tape but these do definitely speed up wrapping
The only downside to these is that the sheets are clear (as well as the seals) so if you put them down its a bit of a challenge to find them (I had four sheets on the go at one point). Also it's hard to see if you've used a sheet up, you have to feel for them or try to catch the light on them to see if there are any left. I wouldn't go out of my way to buy these but they were a nice addition in the Crafty Creatives Christmas Box.
