First try at applique
 

I have decided to give applique a try. I want to do a rooster who's feathers overlap. But now I'm confused about what to use as a fusible. I'll want to stitch the edges down, but after searching Steam-a-Seam info on this Board, it sounds like both can gum up the needle.

I think I want to use the techinque...I hope this makes sense... where you fuse the bonding glue to a piece of fabric, then cut out the applique, and then assemble the pieces on top of a teflon sheet with the pattern underneath so I can get them in the right place, and iron them. I don't think I want to use the pressure type of adhesives.

Does anyone have suggestions about what won't gum up needles?

Just clean your needle with rubbing alcohol every so often.

I've used a few different of the fusible iron on types and none of them have gummed up my needle. Seems like I usually get Heat n Bond light at JoAnns. Although I got some Misty Fuse from a quilt show. Sounds like you have the process pretty well. Iron the fusible onto the back of the fabric and cut out the shape. Sometimes the shape is backwards, then you use a light box to trace your shape. Yes, I have a Teflon ironing sheet to assemble the shapes. I sew with the invisible thread and a skinny zig zag stitch.

Eleanor Burns has a technique where she sews the fusible web to the piece and then turns it inside out and irons the piece to the background - thus giving the appearance of needle turn, then she sews it down. A friend of mine did it - she liked the appearance but felt she was doing everything twice. There was no gummy residue on the needle.
Your idea of using the double sided makes perfect sense.
I have not used Steam a Seam but maybe it is not made for appliqué - just a quick fix for hems. The only time I had a problem with a fusible was when I bought velcro that was peel-n-stick, and thought I would catch the edges with my machine and it did nasty things to my needle. (Had to throw it away that stuff was so stuck.) But I have used Pellon's fusible webs without a problem.

Mckenna Ryan uses that technique. find a you tube of her demonstrating it and note what fusible she uses.

I have used Pellon wonder under with absolutely no issues of gumming up the needle but it can be stiff so I window pane it when doing it as a fusible. But I don't know if you can use the technique you describe. I don't do much fusible applique.

You may want to consider Misty Fuse.

I do tons of appliqué and have been using Heat N Bond Lite for years. I love it. Holds well until I get everything stitched down and stays flexible. It washes away when you launder your finished ( quilted and bound) quilt. It's always my recommendation. I stitch my appliqués with a small blanket stitch or small zigzag- not a fan of heavy/ stiff satin stitch.

I have used Pellon 805 for several years and have never had a problem with it.

I use Soft Fuse. It is so light, it doesn't feel stiff at all and does not gum up the needle. It works well for layering.
