I thought that as I'm not doing anything worthwhile anyway today, I could take a few
Most of the examples -- well, more or less all of them -- use sequin waste with round hole as that's the most common type. You can however find sequin waste in all sorts of shapes. For examples of this, see e.g. Simply Sequins (there's also snowflake-shaped punchinella, but it's out of stock so it doesn't show up in that page -- see it here instead).
First, I just wanted to mention that if you haven't seen it already, you can find some seqiun waste pattern photos in my previous post on the subject. You can also read about what sequin waste or punchinella actually is there.
A good place to start is of cause Flickr, searching for either sequin waste or punchinella. Different names resulting in different search results. Tip: use quotation marks around "sequin waste" for more relevant hits.
Another almost just as good place to start is Pinterest, again search for either sequin waste or punchinella.
In fact, those two places alone will give you many ideas, ranging from printing and scrapbooking to hand embroidery and beadwork.
So far, my favourites are the ones using sequin waste in embroidery. Plenty of examples at Flickr, like this, this, this (bottom right corner) or this (beaded). Notice how some cut open the "centre" to create open flower motifs. More embroideries, using detached daisy stitch, can be found at Pintangle. There's also tiny fragments of sequin waste in the art squares at Taylor's textile trials.
A fabric postcard with sequin waste background and beads and button embellishments can be found at Judy Skeel's blog.
Edited to add: Forgot to mention the videos from Guache Alchemy. One video with 7 different ways of using sequin waste plus a bonus video using embossing and inking.
At Rare Bird, you can see sequin waste being used to create patterns in friendly plastic, e.g. for making necklace pendants. There it's sold as laser mesh. Another version, using two layers, can be seen in Liz Welch's blog here. And don't miss this one either. In this pic, you can see star-shaped sequin waste too. Both sequin waste and sequins in friendly plastic can be found in this post.
Even more pics of friendly plastic and punchinella can be found at Adrienne Wood's blog.
Sequin waste can also be used for weaving as seen e.g. in this preview of a book by Lillian Coppock. Another use for it in the book is for wirework fish, as you could see in that link. More weaving can be found at Julie's mixed media blog.
Mixing punchinella and modelling paste (used with acryclic paints) can result in lovely art pieces like these by Amy Dame.
There are plenty of examples of sequin waste being used as stencils on Flickr so I'm just going to mention JoZart's blog post, showing how she created a background for a concertina file. And some pastel-painted polymer clay at Deez News.
Apparently, it can also be used as a bird scare.
Your turn: have you used sequin waste before? How? Have you found something inspirational online or in books for using this stuff? What would you do with it?
Feel free to add links to pics and blog posts. Your own or other's.
