Seems these would be helpful

saw these this morning and thought wouldn't these be helpful in intarsia work to sand in the small places.

They are, indeed. I bought a few back when I was doing bandsaw boxes.

I have a set of those. I use them on fret work when needed. Because they are manual, I would not use them for shaping though.

I have one of those.  Don't use it very often. It is great for getting corners.

May have to try those.  Looking for anything to help with the sanding now that I am doing lots of interior cuts.

Even the thinnest one may be too big for some cuts. I lay out 6 or 8 skinny popsicle sticks, spray with 3M 77 and cover them with sand paper, then cut them apart. 100 on one side and 150 on the other.

I use emery boards from the discount (dollar) store.  I cut them to fit smaller areas.

Good idea. Thanks.
