This has got to be the prettiest handmade DIY Skate Ornament I’ve come across. It’s made of felt and pipe cleaners. There are more vintage looking felt ornament patterns at the link.
ICE SKATE: Begin top right of boot, button stitch catching hanger. Insert tinsel blade, continue stitching around boot bottom. Stuff, stitch close top of boot. With thread still on needle, tack on fluffy pipe cleaner. Use craft glue to attach sole to boot. Lace boot from bottom up, tie knot, thread string onto needle, pull through pom-poms. Tie knot, slightly pull through to hide string.
There are also these paperclip ice skate ornaments from Poppycock & Other Creative Nonsense here. There’s no DIY, but if you Google “DIY paperclip ice skate ornament” you will find plenty of tutorials.
