I spray mine colored ones with 'sizing' and press with an iron. Spray starch works too on colors but not on anything white. If the item is white use the method below.

Years ago my sister hand crocheted many white snowflakes for her Xmas tree. She used really watered down 'white Elmer's glue' to dip the snowflakes. Then lay flat to dry. This glue mixture prevents the yellowing that spray starch causes. For anything white the glue would be best.

I got Aleene's Stiffen Quik on a recommendation but haven't tried it yet..

I used a product called STIFFY made by Plaid which I got at Joann's and I think Michaels has it, too.

I've used stiffy by plaid on crochet and plan to use on fsl bowls and boxes.

Yes I paint my ornaments with Mod Podge - Gloss Lustre, then while they are wet I sprinkle glitter on them for that extra pizzazz!
