A quilling contest is underway on Instructables.com that has lots of prizes provided by the Silhouette company - 19, in fact, including a custom stamp maker, a Cameo electronic cutting machine, dies, etc. You have plenty of time to make something fabulous and present it as an Instructable; the contest end date is not until July 18.
Read all of the details right here and happy quilling.
Over at AllFreeHolidayCrafts, a Father's Day comment contest is underway through June 17. The site editors selected Karla Lim's popular origami lettering DAD pop-up card that she shared as a guest post here at All Things Paper a few years back as one of the entries.
And while I'm mentioning the AllFreeHolidayCrafts, allow me to also give a shout out to AllFreePaperCrafts.
